Low-amplitude Solar-like Oscillations in the K5 V Star ϵ Indi A

M. Lundkvist, H. Kjeldsen, T. R. Bedding, M. J. McCaughrean et autres

Abstract We have detected solar-like oscillations in the mid-K-dwarf ϵ Indi A, making it the coolest dwarf to have measured oscillations. The star is noteworthy for harboring a pair of brown dwarf companions and a Jupiter-type planet. We observed ϵ Indi A …

Ensemble asteroseismology of pulsating B-type stars in NGC 6910

D. Moździerski, A. Pigulski, Z. Kołaczkowski, G. Michalska et autres

Asteroseismology offers the possibility of probing stellar interiors and testing evolutionary and seismic models. Precise photometry and spectroscopy obtained during multi-site campaigns on young open clusters allows discovering rich samples of pulsating stars and using them in a simultaneous seismic modelling called …

Variability survey in NGC 6910, the open cluster rich in $\beta$ Cephei-type stars

D. Moździerski, A. Pigulski, Z. Kołaczkowski, G. Michalska et autres

NGC 6910 is the northern hemisphere open cluster known to be rich in $\beta$ Cephei-type stars. Using four-season photometry obtained in Bialkow (Poland) and Xinglong (China) observatories, we performed variability survey of NGC 6910. As the result, we found over 100 variable …

An observational asteroseismic study of the pulsating B-type stars in the open cluster NGC 884

S. Saesen, M. Briquet, C. Aerts, A. Miglio et autres

Recent progress in the seismic interpretation of field β Cep stars has resulted in improvements of the physical description in the stellar structure and evolution model computations of massive stars. Further asteroseismic constraints can be obtained from studying ensembles of stars in …

New and updated convex shape models of asteroids based on optical data from a large collaboration network

J. Hanuš, Josef Ďurech, Dagmara Oszkiewicz, R. Behrend et autres

Context. Asteroid modeling efforts in the last decade resulted in a comprehensive dataset of almost 400 convex shape models and their rotation states. These efforts already provided deep insight into physical properties of main-belt asteroids or large collisional families. Going into finer …

Models of red giants in the CoRoT asteroseismology fields combining asteroseismic and spectroscopic constraints

N. Lagarde, A. Miglio, P. Eggenberger, T. Morel et autres

Context. The availability of asteroseismic constraints for a large sample of red giant stars from the CoRoT and Kepler missions paves the way for various statistical studies of the seismic properties of stellar populations.

Detection of solar-like oscillations in the bright red giant starsγPiscium andθ1 Tauri from a 190-day high-precision spectroscopic multi-site campaign

P. G. Beck, Eiji Kambe, M. Hillen, E. Corsaro et autres

Context. Red giants are evolved stars that exhibit solar-like oscillations. Although a multitude of stars have been observed with space telescopes, only a handful of red giant stars were targets of spectroscopic asteroseismic observing projects.

Atmospheric parameters and chemical properties of red giants in the CoRoT asteroseismology fields

T. Morel, A. Miglio, N. Lagarde, J. Montalbán et autres

A precise characterisation of the red giants in the seismology fields of the CoRoT satellite is a prerequisite for further in-depth seismic modelling. High-resolution FEROS and HARPS spectra were obtained as part of the ground-based follow-up campaigns for 19 targets holding great …
