Sector-based morphological analysis of four planetary nebulae (J 320, NGC 2610, A 6672 and PRTM 1) observed with UVIT/ASTROSAT
Anisha Hazra, Ranjan Kumar, Sonika Piridi +1
Four planetary nebulae (PNe), Jonckheere 320, NGC 2610, A 6672, and PRTM 1, have been imaged in the far-ultraviolet (FUV) filter F148W ()…
Exploration of UV-bright sources in Globular cluster NGC 3201 using UVIT observations
Manasi Kulkarni, Sonika Piridi, Ranjan Kumar +1
We present a comprehensive study of the ultraviolet (UV)-bright stellar population in the globular cluster NGC 3201 using the Ultraviolet Imaging Telescope (UVIT) onboard AstroSat.…
Study of Integrated Far-ultraviolet Emissions from Galactic Globular Clusters using AstroSat/UVIT observations
Sonika Piridi, Ranjan Kumar, Divya Pandey +1
We used observations obtained with the Ultraviolet Imaging Telescope on board the AstroSat satellite to measure the integrated far-ultraviolet (FUV) and optical (V) magnitudes of 3…
A Comprehensive Catalog of UVIT Observations I: Catalog Description and First Release of Source Catalog (UVIT DR1)
Sonika Piridi, Ranjan Kumar, Divya Pandey +1
We present the first comprehensive source catalog (UVIT DR1) of ultraviolet (UV) photometry in four far-UV (FUV 13001800 Å) and five near-UV (NUV 20003000 Å) filt…
Discovery of a hot post-AGB star in Galactic globular cluster E3
R. Kumar, A. Moharana, S. Piridi +8
We report a new hot post-asymptotic giant branch (PAGB) star in the Galactic globular cluster (GC) E3, which is one of the first of the identified PAGB stars in a GC to show a bina…
Globular Cluster UVIT Legacy Survey (GlobULeS) II. Evolutionary status of hot stars in M3 and M13
Ranjan Kumar, Ananta C. Pradhan, Snehalata Sahu +4
We present a far-ultraviolet (FUV) study of hot stellar populations in the second parameter pair globular clusters (GCs) M3 and M13, as a part of the Globular cluster UVIT Legacy S…
Study of UV bright sources in globular cluster NGC 4590 using Ultraviolet Imaging Telescope (UVIT) observations
Ranjan Kumar, Ananta C. Pradhan, M. Parthasarathy +5
We have studied ultraviolet (UV) bright sources in the Galactic globular cluster (GGC) NGC 4590 using Ultraviolet Imaging Telescope (UVIT) on-board the \mbox{\em AstroSat} satellit…
Study of Galactic Structure Using UVIT/AstroSat Star Counts
Ranjan Kumar, Ananta C. Pradhan, Devendra K. Ojha +3
The structure of our Galaxy has been studied from ultraviolet (UV) star counts obtained with the Ultra-Violet Imaging Telescope (UVIT) on board the {\em AstroSat} satellite, in Far…
