Physical parameters and wind properties of galactic early B supergiants
, 2006 We present optical studies of the physical and wind properties, plus CNO chemical abundances, of 25 O9.5–B3 Galactic supergiants. We employ non-LTE, line blanketed, extended model atmospheres, which provide a modest downward revision in the effective

ALMA high-resolution observations of Betelgeuse: Persistent structure spanning the inner atmosphere
Astronomy & AstrophysicsContext. The extended atmosphere of red supergiants (RSGs) forms an important link in the process of mass loss and the subsequent enrichment of the interstellar medium.

XMM‐Newton Observations of the Peculiar Be X‐Ray Binary A0538‐66
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT A0538‐66 is a neutron star/Be x‐ray binary located in the Large Magellanic Cloud and, since its discovery in the 70s, it showed a peculiar behavior that makes it a unique object in the high‐mass x‐ray binaries scene: the extremely eccentric orbit (e=0.72$$ e=0.72 $$), the short spin period of the neutron star (P=69$$ P=69 $$ ms), the episodes ...

Peculiar early-type supergiants and LBVs: resemblance and difference [PDF]
, 1997 Peculiar early-type supergiants (hereafter PETS) have been distinguished from normal ones because of stronger emission lines in their spectra. This is a result of different stellar wing kinematics: PETS have slower winds with low terminal velocities ...

Disk Tracing for B[e] Supergiants in the Magellanic Clouds
, 2015 B[e] supergiants are evolved massive stars with a complex circumstellar environment. A number of important emission features probe the structure and the kinematics of the circumstellar material. In our survey of Magellanic Cloud B[e] supergiants we focus

Infrared photometry and mass loss rates for OBA supergiants and Of stars [PDF]
, 1977 We present infrared observations of 34 OBA supergiants and 10 Of and Oe stars. Excess free- free emission is detectable at 10 m but not at shorter wavelengths for the supergiants.

Understanding A-type supergiants - II. Atmospheric parameters and rotational velocities of galactic A-type supergiants [PDF]
, 1999 We present the second paper of a series whose aim is to perform a global study of Galactic A-supergiants. Very little work has been carried out to determine the stellar parameters of these stars.

Beyond Accretion Limits: The Rise of Pulsating Gems
Astronomische Nachrichten, Volume 346, Issue 1, January 2025.ABSTRACT The discovery of several ultraluminous X‐ray sources exhibiting fast and rapidly evolving X‐ray pulsations unequivocally associates these sources with accreting neutron stars orbiting relatively massive companion stars (> 8M ⊙$$ {}_{\odot } $$).
