Super-slowly rotating Ap (ssrAp) stars: New spectroscopic observations

Gautier Mathys, Daniel L. Holdsworth, Marina Giarrusso +2

The rotation periods of Ap stars range over five to six orders of magnitude. The origin of their differentiation remains unknown. We carry out a systematic study of the longest per…

Pulsating and Non-pulsating Components of Detached Eclipsing Binaries in the Scuti instability strip

Filiz Kahraman Aliçavuş, Fahri Aliçavuş, Zeynep Çelik Orhan +3

Pulsating detached eclipsing binary systems are crucial for studying the internal structure of oscillating stars. These systems are advantageous because binary effects on pulsation…

First detection of acoustic-like flux in the middle solar corona

V. Andretta, L. Abbo, G. Jerse +28

Waves are thought to play a significant role in the heating of the solar atmosphere and the acceleration of the wind. Among the many types of waves observed in the Sun, the so-call…

Galactic transient sources with the Cherenkov Telescope Array Observatory

Cherenkov Telescope Array Observatory Consortium

A wide variety of Galactic sources show transient emission at soft and hard X-ray energies: low- and high-mass X-ray binaries containing compact objects, isolated neutron stars exh…

Discovery of the binary nature of the magnetospheric B-type star Oph A

M. E. Shultz, I. Berry, D. Bohlender +11

The nearby B-type star Oph A was recently identified as a rapidly rotating magnetic B-type star with variable radio and X-ray emission consistent with a magnetospheric origin.…
