In orbit performance of UVIT over the 5 years
S. K. Ghosh, P. Joseph, A. Kumar +21
Over the last 5 years, UVIT has completed observations of more than 500 proposals with ~ 800 unique pointings. In addition, regular planned monitoring observations have been made a…
Planetary Nebulae with UVIT: A Progress Report
N. Kameswara Rao, Sutaria F., Murthy J. +2
The spectral region between 1250 Angstroms - 3000 Angstroms contains important spectral lines to understand the morphological structures and evolution of planetary nebulae. This is…
The Horizontal Branch morphology of the globular cluster NGC 1261 using AstroSat
Sharmila Rani, Gajendra Pandey, Annapurni Subramaniam +2
We present the results obtained from the UV photometry of the globular cluster NGC 1261 using Far-UV (FUV) and Near-UV (NUV) images acquired with the Ultraviolet Imaging Telescope…
Detection of CH, CH and H molecules in the Young Planetary Nebula IC 4997
N. Kameswara Rao, David L. Lambert, Arumalla B. S. Reddy +3
We have detected CH and CH molecular absorption lines from the young compact planetary nebula IC 4997 from high resolution optical spectra. A high-resolution infra-red (H and…
SALT revisits DY Cen: a rapidly-evolving strontium-rich single helium star
C. Simon Jeffery, N. Kameswara Rao, David L. Lambert
The hydrogen-deficient star DY Cen has been reported as an R CrB-type variable, an extreme helium star (with some hydrogen), and as a single-lined spectroscopic binary. It has been…
Additional Calibration of the Ultra-Violet Imaging Telescope on board AstroSat
S. N. Tandon, J. Postma, P. Joseph +20
Results of the initial calibration of the Ultra-Violet Imaging Telescope (UVIT) were reported earlier by Tandon et al. (2017). The results reported earlier were based on the ground…
