  A deep XMM-Newton look on the isolated neutron star RX J1605.3+3249 (scientific collaboration), Descrição: The investigation of currently available data suggests that RX J1605.3+3249 may be the neutron star with the highest dipolar field among the "Magnificent Seven" group of isolated neutron stars. Our goals to further investigate the source are to: (i) confirm the spin period and high value of spin-down to investigate a possible evolution from a magnetar; (ii) constrain the geometry of the emitting regions and understand the energy-dependent amplitude of the modulation; (iii) investigate the origin of (broad and narrow) spectral features and the occurrence of harmonics; and (iv) search for signatures of vacuum polarisation and imprints of the crustal magnetic field in the spectrum, pulse shapes, and lightcurves of the source. These goals will be pursued by determining a precise timing solution and performing (phase-resolved and high-resolution) spectroscopy and modelling.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Adriana Mancini Pires - Coordenador / Christian Motch - Integrante / Frank Haberl - Integrante / Axel Schwope - Integrante / ZANE, S. - Integrante / Vyacheslav Zavlin - Integrante., Financiador(es): Deutsches Zentrum für Luft- und Raumfahrt - Remuneração.

  A possible near-infrared counterpart for 2XMM J104608.7-594306 (scientific collaboration), Descrição: 2XMM J104608.7-594306 is one of only two thermally emitting isolated neutron stars (INSs) to be discovered since the ROSAT era. Likely a remnant of a former generation of massive stars in the Carina Nebula, its exact nature is unclear, and it might well occupy a unique role amongst the several groups of Galactic INSs. Very interestingly, we discovered a possible near-infrared counterpart lying inside the error circle of the X-ray source. We propose to observe the field of the neutron star with Chandra with the immediate goal to test the association. The positional accuracy attainable with Chandra will subsequently pave the ground for further investigations in the infrared and X-rays to be carried out, which will considerably constrain the neutron star evolutionary state.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Adriana Mancini Pires - Coordenador / Christian Motch - Integrante / Axel Schwope - Integrante.

  A comprehensive picture of neutron star evolution in the Galaxy (research project), Descrição: The observed population of neutron stars is dominated by radio pulsars. In recent years, however, dierent observational manifestations of isolated neutron stars (INSs) have been discovered, which include magnetars, X-ray dim isolated neutron stars (XDINS) and rotating radio transients (RRATs). In particular, XDINS constitute a homogeneous group of seven nearby, cooling INSs displaying unique properties. While currently fewer in number of detected sources, the peculiar INS subgroups might represent a considerable fraction of the neutron stars in the Galaxy and are very important for a number of reasons. First, the investigation of individual sources can greatly impact our understanding of the physics of matter at extreme conditions of gravity and magnetic field. Second, the relations between the various subgroups help us to understand the main properties determining the neutron star phenomenology. Finally, as new objects are discovered, a comprehensive picture of neutron star birth and evolution in the Milky Way can be aimed for. We propose to investigate the Galactic population of neutron stars, especially focusing on XDINS, in order to characterise neutron star properties and evolutionary state, as well as to understand how the peculiar subgroups relate to each other and to the bulk of the "normal" radio pulsar population. These goals will be pursued by studying further the existing sample of peculiar INSs, by identifying new INS candidates at greater distances and by modeling the creation, evolution and detectability of thermally emitting INSs in the Milky Way with current and future X-ray facilities.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Adriana Mancini Pires - Coordenador / Christian Motch - Integrante / Frank Haberl - Integrante / Axel Schwope - Integrante / Eduardo Janot-Pacheco - Integrante / Sergei Popov - Integrante / Roberto Turolla - Integrante / Aldo Treves - Integrante / Vyacheslav Zavlin - Integrante / Maura Pilia - Integrante / Silvia Zane - Integrante / Markus M.

  Population study of radio-quiet and thermally emitting isolated neutron stars (PhD thesis), Descrição: The main objective of the thesis is to study the properties of the Galactic population of radio-quiet and thermally emitting isolated neutron stars (INSs). This is done by studying further the existing neutron star sample of nearby seven sources, known as the "Magnificent Seven" (M7), as well as by searching for new candidates and constraining possible populations. During the thesis, we investigated the proper motions of three of the faintest M7 in X-rays with the satellite Chandra. This work allowed us to constrain the neutron star displacement in two cases as well as to accurately determine the high proper motion of a third source, for the first time in X-rays with a significance approaching 10 standard deviations. The search of new INS candidates in the serendipitous catalogue of the XMM-Newton Observatory had as well the aim to constrain the spatial density of thermally emitting sources located beyond the solar vicinity. This work allowed the long awaited discovery of a new thermally emitting INS with properties similar to those of the seven nearby sources discovered by ROSAT. Moreover, deep optical observations with SOAR and the ESO-VLT have been obtained during the thesis work in order to optically identify a handful of INS candidates that have been selected among more than 72,000 sources. Finally, population synthesis of Galactic thermally emitting INSs allows constraining the global properties of this population based on the whole sample of XMM-Newton observations. By estimating the density of similar sources at more remote distances in the Milky Way, the final objective is to determine whether the spatial density derived from the group of seven nearby sources is a local anomaly caused by the Sun's current location near regions of active stellar formation of the Gould Belt.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Adriana Mancini Pires - Integrante / Christian Motch - Coordenador / Eduardo Janot Pacheco - Integrante., Financiador(es): Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Bolsa / Fundação de Amparo à Pesquisa do Estado de São Paulo - Bolsa / Centre National de la Recherche Scientifique - Auxílio financeiro., Número de produções C, T & A: 4

  Estudo Óptico-Observacional da Fonte de Raios X Supersoft Galáctica MR Velorum (iniciacao cientifica, trabalho de graduacao), Descrição: Estuda-se as características físicas das fontes supermoles de raios X (SSS), utilizando dados ópticos e em altas energias, no âmbito de um trabalho de IC. Trata-se de binárias que apresentam espectro X muito mole, baixas temperaturas e altas luminosidades bolométricas. Esse sistemas são compostos por uma anã branca realizando fusão em sua superfície, a partir de matéria perdida pela estrela companheira. Os resíduos de fusão se acumulam na superfície da anã branca, e essa pode ultrapassar o limite de Chadrasekhar, produzir um colapso gravitacional, sendo esse um dos cenários propostos para as explosões de SN Ia. Apresentamos nesta comunicação o estado da arte das características físicas das fontes SSS, situando-as no âmbito das VCs. Procuramos também situar esses objetos em relação às variáveis galácticas V Sge, na medida em que os dois grupos apresentam certas caracerísticas bastante semelhantes. A metodologia adotada é aquela pedagógico-cognitiva clássica de um trabalho de IC na área de ciências exatas.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Adriana Mancini Pires - Integrante / Eduardo Janot-Pacheco - Coordenador., Financiador(es): Fundação de Amparo à Pesquisa do Estado de São Paulo - Bolsa., Número de produções C, T & A: 2
