stellar structure and evolution. Through direct observation of rotationally distorted …

Rotational velocities of A-type stars-IV. Evolution of rotational velocities

J Zorec, F Royer - Astronomy & Astrophysics, 2012 - aanda.org
Context. In previous works of this series, we have shown that late B-and early A-type stars
have genuine bimodal distributions of rotational velocities and that late A-type stars lack …

Age determinations of the Hyades, Praesepe, and Pleiades via MESA models with rotation

S Gossage, C Conroy, A Dotter, J Choi… - The Astrophysical …, 2018 - iopscience.iop.org
Abstract The Hyades, Praesepe, and Pleiades are well-studied stellar clusters that anchor
important secondary stellar age indicators. Recent studies have shown that main sequence …

TS Boyajian, HA McAlister, G Van Belle… - The Astrophysical …, 2012 - iopscience.iop.org
We have executed a survey of nearby, main-sequence A-, F-, and G-type stars with the
CHARA Array, successfully measuring the angular diameters of forty-four stars with an …

BCD Spectrophotometry and Rotation of Active B-Type Stars: Theory and Observations

J Zorec - Galaxies, 2023 - mdpi.com
This review has two parts. The first one is devoted to the Barbier–Chalonge–Divan (BCD)
spectrophotometric system, also known as the Paris spectral classification system. Although …

A near-infrared interferometric survey of debris-disc stars-III. First statistics based on 42 stars observed with CHARA/FLUOR

O Absil, D Defrere, VC Du Foresto, E Di Folco… - Astronomy & …, 2013 - aanda.org
Context. Dust is expected to be ubiquitous in extrasolar planetary systems owing to the
dynamical activity of minor bodies. Inner dust populations are, however, still poorly known …

Colder and hotter: interferometric imaging of β Cassiopeiae and α Leonis

X Che, JD Monnier, M Zhao, E Pedretti… - The Astrophysical …, 2011 - iopscience.iop.org
Near-infrared interferometers have recently imaged a number of rapidly rotating A-type stars,
finding levels of gravity darkening inconsistent with theoretical expectations. Here, we …
