V1294 Aql = HD 184279: A bad boy among Be stars or an important clue to the Be phenomenon?
P. Harmanec, H. Božić, P. Koubský +21
A reliable determination of the basic physical properties and variability patterns of hot emission-line stars is important for understanding the Be phenomenon and ultimately, the e…
Variation in solar differential rotation and activity in the period 1964-2016 determined by the Kanzelhöhe data set
I. Poljančić Beljan, R. Jurdana-Šepić, T. Jurkić +8
We determined the differential rotation (DR) parameters and (corresponding to the equatorial rotation velocity and the gradient of the solar DR) by tracing sunspot groups i…
Properties and nature of Be stars 31. The binary nature, light variability, physical elements, and emission-line changes of HD~81357
P. Koubský, P. Harmanec, M. Brož +10
Reliable determination of the basic physical properties of hot emission-line binaries with Roche-lobe filling secondaries is important for developing the theory of mass exchange in…
The chaotic solar cycle II. Analysis of cosmogenic 10Be data
A. Hanslmeier, R. Brajsa, J. Calogovic +6
Context. The variations of solar activity over long time intervals using a solar activity reconstruction based on the cosmogenic radionuclide 10Be measured in polar ice cores are s…
Tracing sunspot groups to determine angular momentum transfer on the Sun
D. Sudar, I. Skokić, D. Ruždjak +2
The goal of this paper is to investigate Reynolds stresses and to check if it is plausible that they are responsible for angular momentum transfer toward the solar equator. We also…
A new ephemeris and an orbital solution of ε Aurigae
Pavel Chadima, Petr Harmanec, Stephenson Yang +9
We collected rich series of RV measurements covering last 110 years and photometric observations from the past 6 primary eclipses, complemented them by our new observations and der…
