The Projected Rotational Velocity Distribution of a Sample of OB stars from a Calibration Based on Synthetic He I Lines
TL;DR: In this paper, a grid of synthetic spectra of He I line profiles was calculated in non-LTE using an extensive helium model atom and updated atomic data for estimating projected rotational velocities of O9-B5 main-sequence stars.

The Milky Way tomography with APOGEE: intrinsic density distribution and structure of mono-abundance populations
Jianhui Lian,Gail Zasowski,Ted Mackereth,Julie Imig,Jon A. Holtzman,Rachael L. Beaton,Jonathan C. Bird,Katia Cunha,J. G. Fern'andez-Trincado,Danny Horta,Richard R. Lane,Karen L. Masters,Christian Nitschelm,Alexandre Roman-Lopes +13 more
TL;DR: In this article , the intrinsic density distribution of MAPs in the Milky Way has been derived by considering the survey selection function and a 2D density model that considers both a broken radial density distribution and radial variation of scale height.
Chemical evolution of fluorine in the bulge , High-resolution K-band spectra of giants in three fields
Henrik Jönsson,Nils Ryde,Graham M. Harper,Katia Cunha,Mathias Schultheis,Kjell Eriksson,Chiaki Kobayashi,Verne V. Smith,Manuela Zoccali +8 more
TL;DR: In this article, the trend of the fluorine-oxygen abundance ratio as a function of a metallicity indicator in the bulge to investigate the possible contribution from Wolf-Rayet stars was determined using spectral fitting.
