A New Age-Activity Relation For Solar Analogs that Accounts for Metallicity
Gabriela Carvalho-Silva, Jorge Meléndez, Anne Rathsam +5
Determining stellar ages is challenging, particularly for cooler main-sequence stars. Magnetic evolution offers an observational alternative for age estimation via the age-chromosp…
The [Y/Mg] chemical clock in the Galactic Disk: The influence of metallicity and Galactic population in the solar neighbourhood
J. Shejeelammal, Jorge Meléndez, Anne Rathsam +1
Stellar ages are an important parameter to study the chemical evolution of the Galaxy. In recent years, several studies have established the existence of a relationship between che…
On the potential of Carbon-Enhanced Metal-Poor stars for Galactic Archaeology
Aruna Goswami, J Shejeelammal, Partha Pratim Goswami +1
The low-mass metal-poor stars in the Galaxy that preserve in their atmosphere, the chemical imprints of the gas clouds from which they were formed can be used as probes to get insi…
Chemodynamical study of two CEMP-no stars from the Hamburg/ESO Survey
J. Shejeelammal, Aruna Goswami
The Carbon-Enhanced Metal-Poor (CEMP) stars with no enhancement of neutron-capture elements, the so-called CEMP-no stars are believed to be the direct descendants of first-generati…
LAMOST J045019.27+394758.7, with peculiar abundances of N, Na, V, Zn, is possibly a Sculptor dwarf galaxy escapee
Meenakshi Purandardas, Aruna Goswami, J. Shejeelammal +5
We present the results of the high-resolution (R60,000) spectroscopic analysis of the star LAMOSTJ045019.27+394758.7 (hereafter J045) from the list of carbon stars of LAMOST…
HCT/HESP study of two carbon stars from the LAMOST survey
J. Shejeelammal, Aruna Goswami, Jianrong Shi
Carbon stars, enhanced in carbon and neutron-capture elements, provide wealth of information about the nucleosynthesis history of the Galaxy. In this work, we present the first eve…
