Stochastic modeling of multiwavelength variability of the classical BL Lac object OJ 287 on timescales ranging from decades to hours
A. Goyal, L. Stawarz, S. Zola +109
We present the results of our power spectral density analysis for the BL Lac object OJ\,287, utilizing the {\it Fermi}-LAT survey at high-energy -rays, {\it Swift}-XRT in X-rays…
Studying the accretion geometry of EXO 2030+375 at luminosities close to the propeller regime
F. Fuerst, P. Kretschmar, J. J. E. Kajava +10
The Be X-ray binary EXO 2030+375 was in an extended low luminosity state during most of 2016. We observed this state with NuSTAR and Swift, supported by INTEGRAL observations as we…
EXO 2030+375 Restarts in Reverse
Peter Kretschmar, Felix Fuerst, Colleen A. Wilson-Hodge +8
The Be X-ray binary pulsar EXO 2030+375, first detected in 1985, has shown a significant detected X-ray outburst at nearly every periastron passage of its 46-day orbit for the past…
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…
