K2 observations of the exoplanet-host star HD 212771
A requirement of our model is that ~40 per cent of main-sequence stars more massive than. ~4.5 Mq must either have magnetic fields in the range of ~ 10-100 G, ...
High-resolution spectroscopy of Vega-like stars - UCL DiscoveryPhotometry and spectroscopy of circumstellar dust in main-sequence stars are powerful tools with which to study extrasolar planetary material. A central ... Discovery of a low-mass companion to the F7V star HD 984We highlight differences in spectral types and intrinsic colors observed in pre-main sequence (pre-MS) stars. Spectral types of pre-MS stars are wavelength- ... The initial spin distribution of B-type stars - Research ExplorerSpectral types as in Table 1 are distinguished by symbols: blue squares. (F-type), green triangles (G-type) and red diamonds (K-type). The solid line in both ... The Character of M Dwarfs - RECONSObservations of main-sequence stars conducted over the last several decades have clearly shown that something like 50percent of stars of spectral types G and F ...

INTRODUCTION 2. OBSERVATIONS AND DATA REDUCTIONThe IRAS data base also contains detec- tions of Vega-like disks around red giant stars that have developed from A and F-type main-sequence stars (Plets et ... Anomalous Spectral Types and Intrinsic Colors of Young StarsIn this review, we focus on ?Solar-type? stars defined as cool main-sequence dwarfs located below the red edge of the classical instability ... DUst around NEarby Stars.
