Abundance analysis of DAZ white dwarfs
Adela Kawka, Stephane Vennes, Frantisek Dinnbier +2
We present an abundance analysis of a sample of 33 hydrogen-rich (DA) white dwarfs. We have used archival high-resolution spectra to measure abundances of calcium, magnesium and ir…
The triple system KR Com
P. Zasche, R. Uhlar
Aims: We present the detailed analysis of triple system KR Com with different observational techniques - photometry, interferometry, and period variation. Methods: The use of BVR p…
The O-type eclipsing binary SZ Cam revisited
Pavel Mayer, Horst Drechsel, Jiří Kubát +1
We analyse new spectra of the multiple system SZ Cam because previous studies found different values of the primary radial velocity amplitude. The older solutions of light curves a…
Space-time segmentation method for study of the vertical structure and evolution of solar supergranulation from data provided by local helioseismology
Radek Zlebcik, Michal Svanda, Mirek Klvana
Solar supergranulation remains a mystery in spite of decades of intensive studies. Most of the papers about supergranulation deal with its surface properties. Local helioseismology…
Searching for Trojan Asteroids in the HD 209458 System: Space-based MOST Photometry and Dynamical Modeling
Reka Moldovan, Jaymie M. Matthews, Brett Gladman +2
We have searched Microvariability and Oscillations of STars (MOST) satellite photometry obtained in 2004, 2005, and 2007 of the solar-type star HD 209458 for Trojan asteroid swarms…
OGLE 2008--BLG--290: An accurate measurement of the limb darkening of a Galactic Bulge K Giant spatially resolved by microlensing
P. Fouque, D. Heyrovsky, S. Dong +115
Gravitational microlensing is not only a successful tool for discovering distant exoplanets, but it also enables characterization of the lens and source stars involved in the lensi…
The field high-amplitude SX Phe variable BL Cam: results from a multisite photometric campaign. II. Evidence of a binary - possibly triple - system
S. Fauvaud, J. -P. Sareyan, I. Ribas +45
Short-period high-amplitude pulsating stars of Population I ( Sct stars) and II (SX Phe variables) exist in the lower part of the classical (Cepheid) instability strip. Most of…
Properties and nature of Be stars: 27. Orbital and recent long-term variations of the Pleiades Be star Pleione = BU Tauri
J. Nemravová, P. Harmanec, J. Kubát +8
Radial-velocity variations of the H-alpha emission measured on the steep wings of the H-alpha line, prewhitened for the long-time changes, vary periodically with a period of (218.0…
DI Her as a test of internal stellar structure and General Relativity: New apsidal motion rate and evolutionary models
A. Claret, G. Torres, M. Wolf
For the past three decades, and until recently, there has been a serious discrepancy between the observed and theoretical values of the apsidal motion rate dw/dt of the eccentric e…
A unified solution for the orbit and light-time effect in the V505 Sgr system
M. Broz, P. Mayer, T. Pribulla +3
The multiple system V505 Sagittarii is composed of at least three stars: a compact eclipsing pair and a distant component, which orbit is measured directly using speckle interferom…
