Li distribution, kinematics and detailed abundance analysis among very metal-poor stars in the Galactic halo from the HESP-GOMPA survey
Avrajit Bandyopadhyay, Thirupathi Sivarani, Timothy C. Beers +3
We present a study on the detailed elemental abundances of newly identified bright very metal-poor stars with the detection of lithium, initially observed as part of the SDSS/MARVE…
Carbon abundance of stars in the LAMOST-Kepler field
Athira Unni, Mayank Narang, Thirupathi Sivarani +5
The correlation between host star iron abundance and the exoplanet occurrence rate is well-established and arrived at in several studies. Similar correlations may be present for th…
Design of an IR Imaging Channel for the Keck Observatory SCALES Instrument
Ravinder K. Banyal, Amirul Hasan, Reni Kupke +14
A next-generation instrument named, Slicer Combined with Array of Lenslets for Exoplanet Spectroscopy (SCALES), is being planned for the W. M. Keck Observatory. SCALES will have an…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
Galactic chemical evolution of exoplanet host stars: Are high-mass planetary systems young?
C. Swastik, Ravinder K. Banyal, Mayank Narang +5
The imprints of stellar nucleosynthesis and chemical evolution of the galaxy can be seen in different stellar populations, with older generation stars showing higher -element ab…
Optical observations and dust modelling of comet 156P/Russell-LINEAR
K. Aravind, Prithish Halder, Shashikiran Ganesh +5
Comet 156P/Russell-LINEAR is a short period Jupiter family comet with an orbital period of 6.44 years. The results from spectroscopic, photometric, polarimetric observations and du…
