Chemistry of TMC-1 with multiply deuterated species and spin chemistry of H2, H2+, H3+ and their isotopologues
L. Majumdar, P. Gratier, M. Ruaud +6
Deuterated species are unique and powerful tools in astronomy since they can probe the physical conditions, chemistry, and ionization level of various astrophysical media. Recent o…
Search for Interstellar monohydric Thiols
Prasanta Gorai, Ankan Das, Amaresh Das +3
It has been pointed out by various astronomers that very interesting relationship exists between interstellar alcohols and the corresponding thiols (sulfur analogue of alcohols) as…
Qualitative observation of reversible phase change in astrochemical ethanethiol ices using infrared spectroscopy
S Pavithraa, R Rajan, P Gorai +7
Here we report the first evidence for a reversible phase change in an ethanethiol ice prepared under astrochemical conditions. InfraRed (IR) spectroscopy was used to monitor the mo…
Images and Spectral Properties of Two Component Advective Flows Around Black Holes: Effects of Photon Bending
Arka Chatterjee, Sandip K. Chakrabarti, Himadri Ghosh
Two component advective flow (TCAF) successfully explains spectral and timing properties of black hole candidates. We study the nature of photon trajectories in the vicinity of a S…
Estimation of Mass of Compact Object in H 1743-322 from 2010 and 2011 Outbursts using TCAF Solution and Spectral Index - QPO Frequency Correlation
Aslam Ali Molla, Sandip K. Chakrabarti, Dipak Debnath +1
The well known black hole candidate H~1743-322 exhibited temporal and spectral variabilities during several outbursts. Daily variation of the accretion rates and the flow geometry…
A New Reference Chemical Composition for TMC-1
P. Gratier, L. Majumdar, M. Ohishi +4
Recent detections of complex organic molecules in dark clouds have rekindled interest in the astrochemical modeling of these environments. Because of its relative closeness and ric…
