Be/X-Ray Binaries: Phenomenology, Variability, and Accretion~Dynamics

Pablo Reig

Be/X-ray binaries constitute the largest and most diverse subgroup of neutron star high-mass X-ray binaries. These systems feature a rapidly rotating Be star surrounded by a circum…

The Mid-infrared Emitting Jet in the Black Hole V404 Cygni in Quiescence

E. S. Borowski, R. I. Hynes, Q. Hunt +13

Observations of some quiescent black hole X-ray binaries have revealed an excess of mid-infrared (MIR) emission above that expected from their donor stars. In one system, V404 Cygn…

Multiwavelength observations of KS 1947+300

Wei Liu, Pablo Reig, Jingzhi Yan +5

KS 1947+300 is a Be/X-ray binary. Despite its nearly circular orbit, it displays both giant and regular less intense X-ray outbursts. According to the viscous decretion disk model,…

Optical counterpart to Swift J0243.6+6124

P. Reig, J. Fabregat, J. Alfonso-Garzón

Swift J0243.6+6124 was discovered during a giant X-ray outburst in October 2017. While there are numerous studies in the X-ray band, very little is known about the optical counterp…

Warped disks during type II outbursts in Be/X-ray binaries: evidence from optical polarimetry

P. Reig, D. Blinov

Current models that explain giant (type II) X-ray outbursts in Be/X-ray binaries (BeXB), are based on the idea of highly distorted disks. They are believed to occur when a misalign…

NuSTAR rules out a cyclotron line in the accreting magnetar candidate 4U2206+54

J. M. Torrejón, P. Reig, F. Fürst +3

Based on our new NuSTAR X-ray telescope data, we rule out any cyclotron line up to 60 keV in the spectra of the high mass X-ray binary 4U2206+54. In particular, we do not find any…
