Mass-Radius relation for magnetized white dwarfs from SDSS
Drisya Karinkuzhi, Banibrata Mukhopadhyay, Dayal Wickramasinghe +1
We present the observational mass-radius (M-R) relation for a sample of 47 magnetized white dwarfs (WDs) with the magnetic field strength (B) ranging from 1 to 773 MG, identified f…
A neutron star candidate in the long-period binary 56 UMa
A. Escorza, D. Karinkuzhi, A. Jorissen +6
56 UMa is a wide binary system that contains a chemically peculiar red giant and a faint companion. Due to its surface chemical abundances, the red giant was classified as a barium…
Chemical analysis of a carbon-enhanced very metal-poor star: CD-27 14351
Drisya Karinkuzhi, Aruna Goswami, Thomas Masseron
We present the first time abundance analysis of a very metal-poor carbon-enhanced star CD-27 14351 based on a high resolution (R ~ 48000) FEROS spectrum. Our abundance analysis per…
Abundance analysis of s-process enhanced barium stars
Upakul Mahanta, Drisya Karinkuzhi, Aruna Goswami +1
Detailed chemical composition studies of stars with enhanced abundances of neutron-capture elements can provide observational constraints for neutron-capture nucleosynthesis studie…
Chemical analysis of CH stars - II: atmospheric parameters and elemental abundances
Drisya Karinkuzhi, Aruna Goswami
We present detailed chemical analyses for a sample of twelve stars selected from the CH star catalogue of Bartkevicius (1996). The sample includes two confirmed binaries, four obje…
Chemical analysis of CH stars - I: atmospheric parameters and elemental abundances
Drisya Karinkuzhi, Aruna Goswami
Results from high-resolution spectral analyses of a selected sample of CH stars are presented. Detailed chemical composition studies of these objects, which could reveal abundance…
