The pulsation modes of the pre-white dwarf PG 1159-035

J. E. S. Costa, S. O. Kepler, D. E. Winget +74

PG 1159-035, a pre-white dwarf with T_eff=140,000 K, is the prototype of both two classes: the PG1159 spectroscopic class and the DOV pulsating class. Previous studies of PG 1159-0…

Light curve analysis of the hybrid sdB pulsators HS0702+6043 and HS2201+2610

R. Lutz, S. Schuh, R. Silvotti +6

We present the detection of low-amplitude, long-period g-modes in two individual sdBV stars which are known to be p-mode pulsators. Only few of these hybrid objects, showing both p…

The Hottest Horizontal-Branch Stars in omega Centauri - Late Hot Flasher vs. Helium Enrichment

S. Moehler, S. Dreizler, T. Lanz +5

UV observations of some massive globular clusters uncovered a significant population of very hot stars below the hot end of the horizontal branch (HB), the so-called blue hook star…

Investigation of transit-selected exoplanet candidates from the MACHO survey

S. D. Huegelmeyer, S. Dreizler, D. Homeier +1

Context: Planets outside our solar system transiting their host star, i. e. those with an orbital inclination near 90 degree, are of special interest to derive physical properties…

Spectral types of planetary host star candidates from OGLE III

S. Dreizler, S. Schuh, D. Homeier

The Optical Gravitational Lensing Experiment project has recently provided the OGLE III list of low-luminosity object transits from campaigns #3 and #4, reporting 40 new objects ex…
