A new sample of warm extreme debris disks from the ALLWISE catalog
Attila Moór, Péter Ábrahám, Gyula Szabó +12
Extreme debris disks (EDDs) are rare systems with peculiarly large amounts of warm dust that may stem from recent giant impacts between planetary embryos during the final phases of…
Spectroscopic confirmation of the binary nature of the hybrid pulsator KIC 5709664 found with the frequency modulation method
A. Derekas, S. J. Murphy, G. Dalya +14
We started a program to search for companions around hybrid Sct/ Dor stars with the frequency modulation method using Kepler data. Our best candidate was KIC 5709664, where…
A New Stellar Atmosphere Grid and Comparisons with HST/STIS Calspec Flux Distributions
Ralph C. Bohlin, Szabolcs Meszaros, Scott W. Fleming +3
The Space Telescope Imaging Spectrograph (STIS) has measured the spectral energy distributions (SEDs) for several stars of types O, B, A, F, and G. These absolute fluxes from the C…
Planet Hunters X. KIC 8462852 - Where's the Flux?
T. S. Boyajian, D. M. LaCourse, S. A. Rappaport +46
Over the duration of the Kepler mission, KIC8462852 was observed to undergo irregularly shaped, aperiodic dips in flux of up to \%. The dipping activity can last for betwe…
HD 183648: a Kepler eclipsing binary with anomalous ellipsoidal variations and a pulsating component
T. Borkovits, A. Derekas, J. Fuller +16
KIC 8560861 (HD 183648) is a marginally eccentric (e=0.05) eclipsing binary with an orbital period of P_orb=31.973d, exhibiting mmag amplitude pulsations on time scales of a few da…
Affordable spectroscopy for 1m-class telescopes
B. Csák, J. Kovács, Gy. M. Szabó +4
Doppler observations of exoplanet systems have been a very expensive technique, mainly due to the high costs of high-resolution stable spectrographs. Recent advances in instrumenta…
HD 181068: A Red Giant in a Triply-Eclipsing Compact Hierarchical Triple System
A. Derekas, L. L. Kiss, T. Borkovits +41
Hierarchical triple systems comprise a close binary and a more distant component. They are important for testing theories of star formation and of stellar evolution in the presence…
Structure and evolution of debris disks around F-type stars: I. Observations, database and basic evolutionary aspects
A. Moór, I. Pascucci, Á. Kóspál +11
Although photometric and spectroscopic surveys with the Spitzer Space Telescope increased remarkably the number of well studied debris disks around A-type and Sun-like stars, detai…
A search for new members of the beta Pic, Tuc-Hor and epsilon Cha moving groups in the RAVE database
L. L. Kiss, A. Moor, T. Szalai +24
We report on the discovery of new members of nearby young moving groups, exploiting the full power of combining the RAVE survey with several stellar age diagnostic methods and foll…
