HD 35502: a hierarchical triple system with a magnetic B5IVpe primary
James Sikora, Gregg Wade, David Bohlender +8
We present our analysis of HD~35502 based on high- and medium-resolution spectropolarimetric observations. Our results indicate that the magnetic B5IVsnp star is the primary compon…
HD 18078: A very slowly rotating Ap star with an unusual magnetic field structure
G. Mathys, I. I. Romanyuk, D. O. Kudryavtsev +3
Context. The existence of a significant population of Ap stars with very long rotation periods (up to several hundred years) has progressively emerged over the past two decades. Ho…
A Five-year Spectroscopic and Photometric Campaign on the Prototypical alpha Cygni Variable and A-type Supergiant Star Deneb
N. D. Richardson, N. D. Morrison, E. E. Kryukova +1
Deneb is often considered the prototypical A-type supergiant, and is one of the visually most luminous stars in the Galaxy. A-type supergiants are potential extragalactic distance…
High resolution spectroscopic study of red clump stars in the Galaxy: iron group elements
E. Puzeras, G. Tautvaisiene, J. G. Cohen +4
The main atmospheric parameters and abundances of the iron group elements (vanadium, chromium, iron, cobalt and nickel) are determined for 62 red giant "clump" stars revealed in th…
