Wiktorowicz,Arthur Vigan,Arthur Vigan,Christian Marois,Inseok Song,Bruce Macintosh,James R. Graham,James R. Graham,René Doyon,Michael S. Bessell,Sandrine Thomas,Olivier Lai +18 more
TL;DR: In this paper, a volume-limited (D 6 75 pc) multiplicity survey of A-type stars was conducted with a combination of adaptive optics imaging and a multi-epoch common proper motion search.

TL;DR: The analysis of the light curves of 48 B-type stars observed by Kepler is presented in this article, including 15 pulsating stars, all of which show low frequencies, characteristic of slowly pulsating B (SPB) stars.

On the Inference of a Star's Inclination Angle from its Rotation Velocity and Projected Rotation Velocity
Kento Masuda,Joshua N. Winn +1 more
TL;DR: In this paper, a method for the probabilistic inference of the inclination of a star's rotation axis based on independent data sets that constrain the star rotation velocity and its projection onto our line of sight is presented.
Journal ArticleDOI
Does Rotation Alone Determine Whether an A-type Star’s Spectrum is Abnormal or Normal?
TL;DR: The principal abnormalities among A-type stars are the metallic-line (Am) and peculiar A (Ap) stars as mentioned in this paper, where diffusion occurs in stars rotating at less than about 120km 8 -1 allowing certain elements to sink and others to rise into the atmosphere.
Journal ArticleDOI
Multiplicity of late-type B stars with HgMn peculiarity
TL;DR: In this article, the multiplicity of chemically peculiar stars, looking for visual companions in the range of angular separation between 0.5 and 1700 AU, was studied. But the results were limited to binary and multiple systems.
