The influence of planetary engulfment on stellar rotation in metal-poor main-sequence stars
A. Oetjens, L. Carone, M. Bergemann +1
The method of gyrochronology relates the age of its star to its rotation period. However, recent evidence of deviations from gyrochronology relations was reported in the literature…
A new survey of cool supergiants in the Magellanic Clouds
Carlos González-Fernández, Ricardo Dorda, Ignacio Negueruela +1
In this study, we conduct a pilot program aimed at the red supergiant population of the Magellanic Clouds. We intend to extend the current known sample to the unexplored low end of…
Optical spectroscopy of MT Dra in 2006 and 2009
A. M. Zubareva, V. V. Shimansky, N. V. Borisov +1
We present low-resolution phase-resolved spectra of the polar MT Dra during its high states in 2006 and 2009. Balmer series, He I and He II 4686 Å emission lines have complex shape…
