Multi-messenger-Athena Synergy White Paper
L. Piro, M. Ahlers, A. Coleiro +30
In this paper we explore the scientific synergies between Athena and some of the key multi-messenger facilities that should be operative concurrently with Athena. These facilities…
High-resolution X-ray spectroscopy of the stellar wind in Vela X-1 during a flare
M. Lomaeva, V. Grinberg, M. Guainazzi +8
We present a 130 ks observation of the prototypical wind-accreting, high-mass X-ray binary Vela X-1 collected with XMM-Newton at orbital phases between 0.12 and 0.28. A stron…
Vela X-1 as a laboratory for accretion in High-Mass X-ray Binaries
P. Kretschmar, S. Martínez-Núñez, F. Fürst +7
Vela X-1 is an eclipsing high mass X-ray binary (HMXB) consisting of a 283s accreting X-ray pulsar in a close orbit of 8.964 days around the B0.5Ib supergiant HD77581 at a distance…
Stellar Winds in Massive X-ray Binaries
Peter Kretschmar, Silvia Martínez-Núñez, Enrico Bozzo +15
Strong winds from massive stars are a topic of interest to a wide range of astrophysical fields. In High-Mass X-ray Binaries the presence of an accreting compact object on the one…
Towards a unified view of inhomogeneous stellar winds in isolated supergiant stars and supergiant high mass X-ray binaries
Silvia Martínez-Núñez, Peter Kretschmar, Enrico Bozzo +13
Massive stars, at least 10 times more massive than the Sun, have two key properties that make them the main drivers of evolution of star clusters, galaxies, and the Universe…
Measuring the stellar wind parameters in IGR J17544-2619 and Vela X-1 constrains the accretion physics in Supergiant Fast X-ray Transient and classical Supergiant X-ray Binaries
A. Gimenez-Garcia, T. Shenar, J. M. Torrejon +9
Classical Supergiant X-ray Binaries (SGXBs) and Supergiant Fast X-ray Transients (SFXTs) are two types of High-mass X-ray Binaries (HMXBs) that present similar donors but, at the s…
GRO J1008-57: an (almost) predictable transient X-ray binary
M. Kühnel, S. Müller, I. Kreykenbohm +13
A study of archival RXTE, Swift, and Suzaku pointed observations of the transient high mass X-ray binary GRO J1008-57 is presented. A new orbital ephemeris based on pulse arrival t…
Another cluster of red supergiants close to RSGC1
Ignacio Negueruela, Carlos Gonzalez-Fernandez, Amparo Marco +2
Recent studies have revealed massive star clusters in a region of the Milky Way close to the tip of the Long Bar. These clusters are heavily obscured and are characterised by a pop…
Correlated X-ray spectral and timing variability of the Be/X-ray binary V0332+53/BQ Cam during a type II outburst
P. Reig, S. Martinez-Nunez, V. Reglero
We have used INTEGRAL & RXTE data to investigate the timing properties of the source in correlation with its spectral states as defined by different positions in the colour-colour…
INTEGRAL-RXTE observations of Cygnus X-1
K. Pottschmidt, J. Wilms, M. Chernyakova +11
We present first results from contemporaneous observations of Cygnus X-1 with INTEGRAL and RXTE, made during INTEGRAL's performance verification phase in 2002 November and December…
