Study of Chemically Peculiar Stars-I : High-resolution Spectroscopy and K2 Photometry of Am Stars in the Region of M44
Santosh Joshi, Otto Trust, E. Semenko +30
We present a study based on the high-resolution spectroscopy and K2 space photometry of five chemically peculiar stars in the region of the open cluster M44. The analysis of the hi…
Ground-based photometric survey to search for the pulsational variability in Bp, Ap, and Am stars
Daniel Nhlapo, Santosh Joshi, Bruno Letarte +2
We present the analysis of time-series of photoelectric data of a Bp star and four new Ap stars observed photoelectrically under the Nainital-Cape survey programme. The project was…
VLT/FLAMES high-resolution chemical abundances in Sculptor: a textbook dwarf spheroidal galaxy
Vanessa Hill, Ása Skúladóttir, Eline Tolstoy +12
We present detailed chemical abundances for 99 red-giant branch stars in the centre of the Sculptor dwarf spheroidal galaxy, obtained from high-resolution VLT/FLAMES spectroscopy.…
Whole Earth Telescope discovery of a strongly distorted quadrupole pulsation in the largest amplitude rapidly oscillating Ap star
Daniel L. Holdsworth, Donald W. Kurtz, Hideyuki Saio +7
We present a new analysis of the rapidly oscillating Ap (roAp) star, 2MASS J (J1940; ). The star was discovered using SuperWASP broadband photometry to ha…
VLT/FLAMES spectroscopy of red giant branch stars in the Fornax dwarf spheroidal galaxy
B. Lemasle, T. de Boer, V. Hill +13
Fornax is one of the most massive dwarf spheroidal galaxies in the Local Group. The Fornax field star population is dominated by intermediate age stars but star formation was going…
Nucleosynthesis and the Inhomogeneous Chemical Evolution of the Carina Dwarf Galaxy
Kim Venn, Matthew Shetrone, Mike Irwin +12
The detailed abundances of 23 elements in nine bright RGB stars in the Carina dSph are presented based on high resolution spectra gathered at the VLT and Magellan telescopes. A sph…
