Evolutionary status of the Of?p star HD148937 and of its surrounding nebula NGC6164/5
L. Mahy, D. Hutsemékers, Y. Nazé +3
Aims. The magnetic star HD148937 is the only Galactic Of?p star surrounded by a nebula. The structure of this nebula is particularly complex and is composed, from the center out ou…
The discovery of a planetary candidate around the evolved low-mass Kepler giant star HD 175370
M. Hrudková, A. Hatzes, R. Karjalainen +20
We report on the discovery of a planetary companion candidate with a minimum mass Msini = 4.6 M_J orbiting the K2 III giant star HD 175370 (KIC 007940959). This star was a target i…
Tracing back the evolution of the candidate LBV HD168625
L. Mahy, D. Hutsemékers, P. Royer +1
Aims. We obtained Herschel/PACS imaging and spectroscopic observations of the nebula surrounding the candidate LBV HD168625. By combining these data with optical spectra of the sta…
Herschel detects oxygen in the beta Pictoris debris disk
A. Brandeker, G. Cataldi, G. Olofsson +28
The young star beta Pictoris is well known for its dusty debris disk, produced through the grinding down by collisions of planetesimals, kilometre-sized bodies in orbit around the…
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…
Herschel observations of the nebula M1-67 around the Wolf-Rayet star WR 124
C. Vamvatira-Nakou, D. Hutsemekers, P. Royer +3
Infrared Herschel imaging and spectroscopic observations of the nebula M1-67 around the Wolf-Rayet star WR 124 have been obtained along with optical imaging observations. The infra…
