Morpho-kinematic and photoionization models of the multipolar structures in planetary nebula NGC 6572
Rahul Bandyopadhyay, Ramkrishna Das, Mudumba Parthasarathy +1
We have studied the planetary nebula (PN) NGC 6572 through 3D morpho-kinematic and photoionization modelling. The 3D morphology is reconstructed from the Hubble Space Telescope ima…
Evolutionary status of selected post-AGB stars based on Gaia DR3 data
M. Parthasarathy, Marina. Kounkel, Keivan G. Stassun
The evolutionary status of 24 post-AGB stars is presented based on Gaia DR3 data. All 24 stars have parallaxes accurate to better than 3 X sigma and have RUWE values less than 1.4.…
Gaia DR2 and EDR3 data and evolutionary status of post-AGB stars with high radial velocities
Wako Aoki, Tadafumi Matsuno, Mudumba Parthasarathy
Using the Gaia DR2 and EDR3 data and list of post-AGB candidates, we investigate the parallax, proper motion and binarity for twenty post-AGB stars and candidates having high radia…
Evolution of Hen\,3-1357, the Stingray Nebula
Miriam Peña, Mudumba Parthasarathy, Francisco Ruiz-Escobedo +1
The spectroscopic evolution of Hen\,3-1357, the Stingray Nebula, is presented by analysing data from 1990 to 2021. High resolution data obtained in 2021 with South African Large Te…
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…
Ultraviolet Imaging Telescope (UVIT) observation of the Galactic Globular Cluster NGC 7492
Ranjan Kumar, Ananta C. Pradhan, Abhisek Mohapatra +4
We present detailed photometric observations of the Galactic globular cluster NGC 7492 using the data obtained with two far-ultraviolet (FUV: 1300 - 1800 Å) and three near-ultravio…
