Whole Earth Telescope Observations of the subdwarf B star KPD 1930+2752: A rich, short period pulsator in a close binary
M. D. Reed, S. L. Harms, S. Poindexter +58
KPD 1930+2752 is a short-period pulsating subdwarf B (sdB) star. It is also an ellipsoidal variable with a known binary period just over two hours. The companion is most likely a w…
Self organized criticality in an improved Olami-Feder-Christensen model
Gui-Qing Zhang, Ugur Tirnakli, Lin Wang +1
An improved version of the Olami-Feder-Christensen model has been introduced to consider avalanche size differences. Our model well demonstrates the power-law behavior and finite s…
Differential rotation on the young solar analogue V889 Herculis
Zsolt Kovari, Antonio Frasca, Katia Biazzo +3
V889 Herculis is one of the brightest single early-G type stars, a young Sun, that is rotating fast enough (P_rot =1.337 days) for mapping its surface by Doppler Imaging. The 10 FO…
Observations of Faint Eclipsing Cataclysmic Variables
Dicle Zengin Çamurdan, Cafer İbanoğlu, C. Muzaffer Çamurdan
We present time-resolved photometry of six faint (V>17mag) cataclysmic variables (CVs); one of them is V849 Oph and the others are identified from the Sloan Digital Sky Survey (SDS…
Some anisotropic universes in the presence of imperfect fluid coupling with spatial curvature
Ozgur Akarsu, Can B. Kilinc
We consider Bianchi VI spacetime, which also can be reduced to Bianchi types VI0-V-III-I. We initially consider the most general form of the energy-momentum tensor which yields ani…
Photospheric and chromospheric activity on the young solar-type star HD 171488
A. Frasca, K. Biazzo, Zs. Kovari +2
We present the results of contemporaneous spectroscopic and photometric monitoring of the young solar-type star HD171488 (Prot~1.337 d) aimed at studying surface inhomogeneities at…
