Polycyclic aromatic hydrocarbon (PAH) abundances in the disk around T Chamaeleontis (T Cha): PAH sizes, ionization fraction, and mass during JWST observations
Rahul Bandyopadhyay, Simon Casassus
The T Tauri star T Cha is known to have a protoplanetary disk with a dust gap separating the inner and outer disk regions. The mid-infrared JWST spectrum of T Cha shows multiple pr…
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…
Study of 2021 outburst of the recurrent nova RS Ophiuchi: Photoionization and morpho-kinematic modelling
Ruchi Pandey, Gesesew R. Habtie, Rahul Bandyopadhyay +3
We present the evolution of the optical spectra of the 2021 outburst of RS Ophiuchi (RS Oph) over about a month after the outburst. The spectral evolution is similar to the previou…
Compact planetary nebulae MaC 2-1 and Sp 4-1: Photoionization models and dust characteristics
Rahul Bandyopadhyay, Ramkrishna Das, Soumen Mondal
We study the characteristics of planetary nebulae (PNe), MaC 2-1 and Sp 4-1. We use our optical spectra taken at 2 m Himalayan Chandra Telescope, Spitzer mid-infrared (mid-IR) spec…
Morphology and ionization characteristics of planetary nebulae PB 1 and PC 19
Rahul Bandyopadhyay, Ramkrishna Das, Soumen Mondal +1
We present results of our study of two planetary nebulae (PNe), PB1 and PC 19. We use the optical spectra of these two PNe observed at 2 m Himalayan Chandra Telescope and also arch…
