The changing optical and X-ray emission of the dormant Cas star HD 45314
G. Rauw, Y. Nazé, E. Bryssinck +25
Cas stars are Oe/Be stars that exhibit bright and hard X-ray emission. HD45314 belonged to this category, but lost its Cas characteristics as its circumstellar disc started…
Testing the theory of colliding winds: The periastron passage of 9 Sagittarii. II. Radio monitoring
R. Blomme, G. Rauw, D. Volpi +2
Colliding winds in massive-star binaries generate non-thermal radio emission and an increased X-ray emission. We study the radio emission of the non-thermal emitter 9 Sgr, which is…
The birth of Be star disks I. From localized ejection to circularization
J. Labadie-Bartz, A. C. Carciofi, A. C. Rubio +35
Classical Be stars are well known to eject mass, but the details governing the initial distribution and evolution of this matter into a disk are poorly constrained by observations.…
X-raying the wind-wind collisions in HD 168112 and HD 167971
Gregor Rauw, Ronny Blomme, Yaël Nazé +1
The O-type long-period binary HD 168112 and triple HD 167971 star systems have been known for several decades for their non-thermal synchrotron radio emission. This emission arises…
TESS observations of non-Be fast rotators
Yael Naze, Nikolay Britavskiy, Jonathan Labadie-Bartz
The variability of fast-rotating Oe/Be stars has been reported in detail in recent years. However, much less known about the behaviour of fast-rotating OB stars without known decre…
Ups and downs in the X-ray emission of the colliding wind binaries HD 168112 and HD 167971
Gregor Rauw, Ronny Blomme, Yael Naze +2
The long-period O-star binary system HD 168112 and the triple O-star system HD 167971 are well-known sources of non-thermal radio emission that arises from a colliding wind interac…
