Planet population synthesis: The role of stellar encounters
Nelson Ndugu, Oyirwoth Patrick Abedigamba, Geoffrey Andama
Depending on the stellar densities, protoplanetary discs in stellar clusters undergo background heating, disc truncation-driven by stellar encounter, and photo-evaporation. Disc tr…
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…
Differential rotation in K, G, F and A stars
Luis A. Balona, Oyirwoth P. Abedigamba
Rotational light modulation in Kepler photometry of K - A stars is used to estimate the absolute rotational shear. The rotation frequency spread in 2562 carefully selected stars wi…
Spots on Am stars
L. A. Balona, G. Catanzaro, O. P. Abedigamba +2
We investigate the light variations of 15 Am stars using four years of high-precision photometry from the Kepler spacecraft and an additional 14 Am stars from the K2 Campaign 0 fie…
Is there a metallicity gradient in the LMC?
Michael W Feast, Oyirwoth P Abedigamba, Patricia A Whitelock
A small but significant radial gradient in the mean periods of LMC RR Lyrae variables is established from the OGLEIII survey data. This is interpreted as a metallicity gradient but…
