The rotation rate of solar active and ephemeral regions -- I. Dependence on morphology and peak magnetic flux
Alexander S. Kutsenko
Using magnetic field maps acquired by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory we measured rotation rates of 864 active and 322 ephemeral region…
The effect of magnetic field on the damping of slow waves in the solar corona
T. J. Duckenfield, D. Y. Kolotkov, V. M. Nakariakov
Slow magnetoacoustic waves are routinely observed in astrophysical plasma systems such as the solar corona. As a slow wave propagates through a plasma, it modifies the equilibrium…
Long-Term Activity in Photospheres of Low-Mass Stars with Strong Magnetic Fields
N. I. Bondar', M. M. Katsova
The behavior of the average annual luminosity of K-M dwarfs OU Gem, EQ Vir, V1005 Ori and AU Mic was studied at time intervals of several decades. The main sources of photometric d…
Superfast Line Profile Variations in the Spectra of OBA Stars III: A0 Star CVn, New Results
A. F. Kholtygin, A. V. Moiseeva, I A. Yakunin +1
This work is a continuation of the studies of the ultrafast variability of line profiles in the spectra of early-type stars. Line profile variations (LPVs) in the spectrum a chemic…
High-resolution optical spectroscopy of the post-AGB supergiant V340 Ser (=IRAS 172791119)
V. G. Klochkova, V. E. Panchuk, N. S. Tavolzhanskaya +1
Some evidences of wind variability and velocity stratification in the extended atmosphere has been found in the spectra of the supergiant V340 Ser (=IRAS 172791119) taken at the…
Seismological constraints on the solar coronal heating function
D. Y. Kolotkov, T. J. Duckenfield, V. M. Nakariakov
The hot solar corona exists because of the balance between radiative and conductive cooling and some counteracting heating mechanism which remains one of the major puzzles in solar…
