A. F. Kholtygin, I. Ya. Yakunin, V. S. Bukharinov +3
The present paper is devoted to studying the variability of the Cas type star SAO 49725. Both the optical and X-ray spectra of the star are analyzed. Variability of line profil…
The near-infrared companion to HD94660 (=KQ Vel)
M. Schöller, C. A. Hummel, S. Hubrig +4
The Bp star HD94660 is a single-lined spectroscopic binary. Some authors have suggested that the unseen companion of at least 2M_sun may be a compact object. We intend to study thi…
A short and sudden increase of the magnetic field strength and the accompanying spectral variability in the O9.7V star HD54879
S. Hubrig, M. Kueker, S. P. Jarvinen +4
Only eleven O-type stars have been confirmed to possess large-scale organized magnetic fields. The presence of a -600G longitudinal magnetic field in the O9.7V star HD54879 with a…
Optical observations of PSR J2021+3651 in the Dragonfly Nebula with the GTC
Aida Kirichenko, Andrey Danilenko, Peter Shternin +7
PSR J2021+3651 is a 17 kyr old rotation powered pulsar detected in the radio, X-rays, and -rays. It powers a torus-like pulsar wind nebula with jets, dubbed the Dragonfly, which…
