Multiwavelength monitoring of BD+53 2790, the optical counterpart to 4U~2206+54
P. Blay, I. Negueruela, P. Reig +4
We present the results of our long-term monitoring of BD+53 2790, the optical counterpart to the X-ray source 4U~2206+54. Unlike previous studies that classify the source as a Be/X…

Discovery of a Transition to Global Spin-up in EXO 2030+375
Colleen A. Wilson, Juan Fabregat, Wayne Coburn
EXO 2030+375, a 42-second transient X-ray pulsar with a Be star companion, has been observed to undergo an outburst at nearly every periastron passage for the last 13.5 years. From…
