Long-term photometric monitoring of the hybrid subdwarf B pulsator HS0702+6043
R. Lutz, S. Schuh, R. Silvotti +2
Pulsating subdwarf B stars oscillate in short-period -modes or long-period -modes. HS 0702 + 6043 is one of currently three objects known to show characteristics of both type…
Multi-wavelength photometric variation of PG1605+072
S. Schuh, S. Dreizler, U. Heber +8
In a large coordinated attempt to further our understanding of the -mode pulsating sdB star PG1605+072, the Multi-Site Spectroscopic Telescope (MSST) collaboration has obtained…
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…
