Fast time optical variability in Be/X-ray binaries. Pulsation and rotation
P. Reig, J. Fabregat
Classical Be stars, regardless of spectral subtype, display multiperiodic light modulations in the frequency range 0.1-12 d, when observed with high-cadence and long duratio…
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…
IGAPS: the merged IPHAS and UVEX optical surveys of theNorthern Galactic Plane
M. Monguió, R. Greimel, J. E. Drew +47
The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003 an…
Long-term optical and X-ray variability of the Be/X-ray binary H 1145-619: discovery of an on-going retrograde density wave
J. Alfonso-Garzón, J. Fabregat, P. Reig +7
Multiwavelength monitoring of Be/X-ray binaries is crucial to understand the mechanisms producing their outbursts. H 1145-619 is one of these systems, which has recently displayed…
Physical parameters of IPHAS-selected classical Be stars. (I. Determination procedure and evaluation of the results.)
L. Gkouvelis, J. Fabregat, J. Zorec +5
We present a semi-automatic procedure to obtain fundamental physical parameters and distances of classical Be (CBe) stars, based on the Barbier-Chalonge-Divan (BCD) spectrophotomet…
North Galactic plane structure with IPHAS Be stars
Leo Gkouvelis, Juan Fabregat, the IPHAS consortium
Our goal is to investigate the spiral structure of the Northern Galactic plane using as tracers the classical Be stars detected by INT Photometric H Survey (IPHAS). IPHAS scans…
