How much Metal does the Quiet Sun Corona contain?
XSM onboard Chandrayaan-2 observed the Sun during the deepest solar minimum of the past century from in 2019-2020. By studying the XSM spectra for the days when the Sun was very quiet, researchers have found that the abundances of all...
EARTH-SIZED TELESCOPES FOR ASTRONOMICAL OBSERVATIONS IN THE LOW RADIO FREQUENCIES
The study of the cosmos is only complete when we can receive and analyse data from the entire electromagnetic spectrum, ranging from picometer-sized gamma rays to several meters long radio waves. This realization is what led to the advent of...
Identifying emission-line stars from a large spectroscopic database
We present a catalog of 3339 hot emission-line stars (ELS) identified from 451,695 O, B, and A type spectra, provided by the LAMOST DR5 release. We developed an automated python routine that identified 5437 spectra having a peak between 6561...
Bengaluru: The Astronomy City
As part of the National Science day celebrations, the Indian Institute of Astrophysics organised a panel discussion titled- Bengaluru The Astronomy City. The focus of the meeting was to educate the young students regarding various opportunities in astronomy and astrophysics...
Understanding the evolution of the binary star system ‘Cen X-3’: New measurements of the spin and orbital parameters of the system
Researchers from Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, present the new measurements of the spin and orbital parameters of the binary star system ‘Cen X-3’. This work is a step forward in understanding the complex dynamics of the...
Understanding the solar chromosphere through spectral lines
This article takes the reader through a journey of inferring the cosmos - specifically our dear neighbour Sun - through various properties of light. The journey meanders through our work on understanding solar chromospheric properties through spectral lines, and seems...
