Near infra-red spectroscopy of V838 Monocerotis
D. P. K. Banerjee, N. M. Ashok
Near IR, multi-epoch, spectroscopic and photometric observations of the enigmatic, eruptive variable V838 Mon in JHK bands are reported. One of the unusual features is the detectio…
Determination of Substellar Mass Function of Young Open Clusters Using 2MASS and GSC Data
Anandmayee Tej, Kailash C. Sahu, T. Chandrasekhar +1
We present a statistical method to derive the mass functions of open clusters using sky survey data such as the 2 Micron All Sky Survey and the Guide Star Catalogue. We have used t…
Substellar Mass Function of Young Open Clusters as Determined through a Statistical Approach Using 2MASS and GSC Data
Anandmayee Tej, Kailash C. Sahu, T. Chandrasekhar +1
In this paper we present the mass functions in the substellar regime of three young open clusters, IC 348, Orionis and Pleiades, as derived using the data from the 2 Micron All…
Hydrodynamical Study of Advective Accretion flow around Neutron Stars
Banibrata Mukhopadhyay
Here we study the accretion process around a neutron star, especially for the cases where shock does form in the accretion disk. In case of accretion flows around a black hole, clo…
Low resolution spectroscopy of ISOGAL sources: Search for early-type stars with infrared excess
M. Schultheis, M. Parthasarathy, A. Omont +4
An analysis of low resolution spectra and infared data of 29 ISOGAL-DENIS sources with mid-IR excess is presented. Eight ISOGAL sources from our sample with 7-15 micron excess are…
