Rotation and lithium abundance of solar-analog stars: Theoretical analysis of observations
(Astronomy & Astrophysics, 2010)
The lithium-rotation connection in the newly discovered young stellar stream Psc-Eri (Meingast 1)
(European Southern Observatory, 2020)
Context. As a fragile element, lithium is a sensitive probe of physical processes occurring in stellar interiors.
Aims. We aim to investigate the relationship between lithium abundance and rotation rate in low-mass members ...
Rotationally modulated variations and the mean longitudinal magnetic field of the Herbig Ae star HD 101412
(Edp Sciences, 2011-01)
Context. Despite the importance of magnetic fields to a full understanding of the properties of accreting Herbig Ae/Be stars, these fields have scarcely been studied until now over the rotation cycle. One reason for the ...
A catalog of rotational and radial velocities for evolved starsA catalog of rotational and radial velocities for evolved stars
(EDP Sciences, 2006-07-20)
Aims.The present paper describes the first results of an observational program intended to refine and extend the existing measurements of metal-poor stars, with an emphasis on field evolved stars. Methods.The survey was ...

Ground-based detection of G star super ares with NGTS
(Oxford University Press, 2018-07)
We present high cadence detections of two superflares from a bright G8 star (V = 11.56) with the Next Generation Transit Survey (NGTS). We improve upon previous superflare detections by resolving the flare rise and peak, ...
