A test for the theory of colliding winds: the periastron passage of 9 Sagittarii I. X-ray and optical spectroscopy
Gregor Rauw, Ronny Blomme, Yael Naze +7
The long-period, highly eccentric O-star binary 9 Sgr, known for its non-thermal radio emission and its relatively bright X-ray emission, went through its periastron in 2013. Such…
HD45314: a new gamma Cas analog among Oe stars
G. Rauw, Y. Naze, M. Spano +2
Oe stars possibly form an extension to higher temperatures of the Be phenomenon, but it is still unclear whether these stars have disks. X-ray spectra could provide hints for inter…
9 Sgr: uncovering an O-type spectroscopic binary with an 8.6 year period
G. Rauw, H. Sana, M. Spano +4
The O-type object 9 Sgr is a well-known synchrotron radio emitter. This feature is usually attributed to colliding-wind binary systems, but 9 Sgr was long considered a single star.…
Long Period Variables in the Large Magellanic Cloud from the EROS-2 survey
M. Spano, N. Mowlavi, L. Eyer +4
Context. The EROS-2 survey has produced a database of millions of time series from stars monitored for more than six years, allowing to classify some of their sources into differen…
Long Period Variables in the Magellanic Clouds with EROS-2 survey
M. Spano, N. Mowlavi, L. Eyer +2
We use the EROS-2 database to analyze Long Period Variables (LPVs) in the Magellanic Clouds. It results in the creation of a catalog of more than 40 000 LPV candidates which is bri…
New findings on the prototypical Of?p stars
Y. Naze, A. ud-Doula, M. Spano +3
In recent years several in-depth investigations of the three Galactic Of?p stars were undertaken. These multiwavelength studies revealed the peculiar properties of these objects (i…
