Journal ArticleDOI
The Stellar Parameters and Evolutionary State of the Primary in the d'-Symbiotic System StH\alpha190
TL;DR: In this paper, a high-resolution, spectroscopic stellar parameter and abundance analysis of a d' symbiotic star: the yellow component of StH\alpha190 was performed.
Journal ArticleDOI
High-resolution spectroscopic observations of the D${'}$-type symbiotic stars HD 330036 and AS 201
TL;DR: In this article, high-resolution spectroscopic analyses of two stars classified as D -type symbiotic stars, HD 330036 and AS 201, were presented, showing both rapid rotation and enhancements of the s-process elements that are synthesized via slow neutron captures during stellar evolution along the asymptotic giant branch (AGB).

TL;DR: In this article, the infrared spectra of the newly discovered brown dwarf Ind Ba were analyzed at a resolution of λ/Δλ = R = 50,000 and the physical parameters of effective temperature and surface gravity were derived by comparison with model spectra calculated from atmospheres computed using unified cloudy models.
Journal ArticleDOI
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.

TL;DR: In this article, an elemental abundance analysis of high-resolution spectra for five giant stars spatially located within the innermost regions of the bulge globular cluster NGC 6522 and derive Fe, Mg, Al, C, N, O, Si, and Ce abundances based on H-band spectra taken with the multi-object APOGEE-north spectrograph from the SDSS-IV Apache Point Observatory Galactic Evolution Experiment (APOGEE) survey.
