The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
A family of binaries with an extreme mass ratio
Yael Naze, Gregor Rauw, Piotr A. Kolaczek-Szymanski +2
Multiplicity is ubiquitous among massive stars. While the stellar components usually display similar masses, some binaries with extremely low mass ratios were also observed. Some o…
Apsidal motion and proximity effects in the massive binary BD+60 497
Gregor Rauw, Piotr A. Kolaczek-Szymanski, Yael Naze +1
The eccentric short-period O-star binary BD+60 497 is an interesting laboratory in which to study tidal interactions in massive binary systems, notably via the detection and charac…
High energy emission powered by accreting companions of Be/gamma Cas stars
Rina G. Rast, Yael Naze, Jonathan Labadie-Bartz +6
The origin of the hard, bright X-ray emission that defines the gamma Cas analog class of Be stars remains an outstanding question in Be star literature. This work explores the poss…
X-ray Polarimetry of Accreting White Dwarfs: A Case Study of EX Hydrae
Sean J. Gunderson, Swati Ravi, Herman L. Marshall +5
We present the first first X-ray polarization measurements of a white dwarf, the intermediate polar EX Hya. We measured significant polarization only in the 2 -- 3 keV energy band…
The multi-faceted variability of HD 192639: Stochastic behaviour, regularities, and an exceptional mass-ejection event
Gregor Rauw, Yaël Nazé, Charles-Antoine Gilon
Spectroscopic and photometric variability is widespread among O-type supergiants. It is linked to various phenomena affecting the star and its circumstellar environment, thereby pr…
