Possibilities of Identifying Members from Milky Way Satellite Galaxies using Unsupervised Machine Learning Algorithms
Devika K Divakar, Pallavi Saraf, Sivarani Thirupathi +1
A detailed study of stellar populations in Milky Way (MW) satellite galaxies remains an observational challenge due to their faintness and fewer spectroscopically confirmed member…
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…
Magnetic imprints of eruptive and non-eruptive Solar flares as observed by Solar Dynamics Observatory
N. Vasantharaju, P. Vemareddy, B. Ravindra +1
The abrupt and permanent changes of photospheric magnetic field in the localized regions of active regions during solar flares called magnetic imprints (MIs), have been observed fo…
Finding the critical decay index in solar prominence eruptions
N. Vasantharaju, P. Vemareddy, B. Ravindra +1
The background field is assumed to play prime role in the erupting structures like prominences. In the flux rope models, the critical decay index () is a measure of the rate a…
Formation and eruption of sigmoidal structure from a weak field region of NOAA 11942
N. Vasantharaju, P. Vemareddy, B. Ravindra +1
Using observations from Solar Dynamics Observatory, we studied an interesting example of a sigmoid formation and eruption from small-scale flux canceling regions of active region (…
Statistical study of magnetic non-potential measures in confined and eruptive flares
N. Vasantharaju, P. Vemareddy, B. Ravindra +1
Using the HMI/SDO vector magnetic field observations, we studied the relation of degree of magnetic non-potentiality with the observed flare/CME in active regions. From a sample of…
