Flare Activity and Magnetic Feature Analysis of the Flare Stars II: Sub-Giant Branch
Hadis Goodarzi, Ahmad Mehrabi, Habib G. Khosroshahi +1
We present an investigation of the magnetic activity and flare characteristics of the sub-giant stars mostly from F and G spectral types and compare the results with the main-seque…
Flare Activity and Magnetic Feature Analysis of the Flare Stars
Hadis Goodarzi, Ahmad Mehrabi, Habib khosroshahi +1
We analyze the light curve of 1740 flare stars to study the relationship between the magnetic feature characteristics and the identified flare activity. Coverage and stability of m…
Magnetic activity analysis for a sample of G-type main sequence \emph{Kepler} targets
A. Mehrabi, H. He, H. Khosroshahi
The variation of a stellar light curve owing to the rotational modulation by the magnetic features (starspots and faculae) on the star's surface can be used to investigate the magn…
On the possibility of magnetic field detection on a microlensed source star
Ahmad Mehrabi, Habib khosroshahi, Hadi Rahmani
In a microlensing event, a large magnification occurs at caustic crossing and provides an opportunity to obtain a stronger signal associated with the object. In this paper we study…
The UK Infrared Telescope M33 monitoring project. IV. Variable red giant stars across the galactic disc
Atefeh Javadi, Maryam Saberi, Jacco Th. van Loon +3
We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope (UKIRT), of the Local Group spiral galaxy M33 (Triangulum). The main aim was to identify stars in…
The Age and The Mass of The αHerculis Triple-Star System From A MESA Grid of rotating stars with 1.3 <= M/Msun <= 8.0
Ehsan Moravveji, Edward F. Guinan, Habib G. Khosroshahi +1
α^1 Her is the second closest Asymptotic Giant Branch (AGB) star to the Sun, and the variable luminous M5 Ib-II member of a triple stellar system containing G8 III and A9 IV-V comp…
The UK Infrared Telescope M33 monitoring project. III. Feedback from dusty stellar winds in the central square kiloparsec
Atefeh Javadi, Jacco Th. van Loon, Habib Khosroshahi +1
We have conducted a near-infrared monitoring campaign at the UK InfraRed Telescope (UKIRT), of the Local Group spiral galaxy M33 (Triangulum). The main aim was to identify stars in…
