Multi-wavelength quasi-periodic pulsations in a stellar superflare
Dmitrii Y. Kolotkov, Valery M. Nakariakov, Robin Holt +1
We present the first multi-wavelength simultaneous detection of QPP in a superflare (more than a thousand times stronger than known solar flares) on a cool star, in soft X-rays (SX…
Photometric and spectroscopic analysis of LBV candidate J004341.84+411112.0 in M31
A. Sarkisyan, O. Sholukhova, S. Fabrika +4
We study Luminous Blue Variable (LBV) candidate J004341.84+411112.0 in the Andromeda galaxy. We present optical spectra of the object obtained with the 6-m telescope of SAO RAS. Th…
Signature of the turbulent component of solar dynamo on active region scales and its association with flaring activity
Valentina I. Abramenko
Obtaining observational evidence of the turbulent component of solar dynamo operating in the convective zone is a challenging problem because the dynamo action is hidden below the…
The solar corona as an active medium for magnetoacoustic waves
D. Y. Kolotkov, D. I. Zavershinskii, V. M. Nakariakov
The presence and interplay of continuous cooling and heating processes maintaining the corona of the Sun at the observed one million K temperature were recently understood to have…
Study of Chemically Peculiar Stars-I : High-resolution Spectroscopy and K2 Photometry of Am Stars in the Region of M44
Santosh Joshi, Otto Trust, E. Semenko +30
We present a study based on the high-resolution spectroscopy and K2 space photometry of five chemically peculiar stars in the region of the open cluster M44. The analysis of the hi…
Kink oscillations of coronal loops
V. M. Nakariakov, S. A. Anfinogentov, P. Antolin +13
Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy re…
