Asteroseismology provides us with a unique opportunity to improve our understanding of stellar structure and evolution. Recent developments, including the first...
Asteroseismology of OB stars with hundreds of single snapshot spectra (and a few time-series of selected targets)
Imagine we could do asteroseismology of large samples of OB-type stars by using just one spectrum per target. That would be great! But this is probably a crazy...
Asteroseismology of the Hyades red giant and planet host ɛ Tauri⋆
Context. Asteroseismic analysis of solar-like stars allows us to determine physical parameters such as stellar mass, with a higher precision compared to most...
Asteroseismology of the β Cephei star 12 (DD) Lacertae: photometric observations, pulsational frequency analysis and mode identification
We report a multisite photometric campaign for the β Cephei star 12 Lacertae. 750 h of high-quality differential photoelectric Strömgren, Johnson and Geneva...
Asteroseismology of the β Cephei star ν Eridani - II. Spectroscopic observations and pulsational frequency analysis
We undertook a multisite spectroscopic campaign for the β Cephei star ν Eridani. A total of 2294 high-resolution spectra were obtained from telescopes at 11...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - I. The Pleiades
We present the results of a deep wide-field near-infrared survey of the entire Pleiades cluster recently released as part of the UKIRT Infrared Deep Sky Survey...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - II. The Alpha Persei open cluster
We present the results of a deep (J = 19.1 mag) infrared (ZY JHK) survey over the full α Per open cluster extracted from the Data Release 9 of the United...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - III. Praesepe
Over the past decades open clusters have been the subject of many studies. Such studies are crucial considering that the universality of the initial mass...
Astrometric and photometric initial mass functions from the UKIDSS Galactic Clusters Survey - IV. Upper Sco
We present the results of a proper motion wide-field near-infrared survey of the entire Upper Sco (USco) association (˜160 square degrees) released as part of...
