Angular diameter measurements of evolved variables by lunar occultations at 2.2 and 3.8 micron (2005)

Mondal, Soumen, Chandrasekhar, T.

We report the angular diameters of two Mira variables (U Ari and Z Sco), three semiregular (SR) and irregular variables (SW Vir, eta Gem and mu Gem) and a supergiant SR variable (TV Gem) by lunar...

SS 433: Results of a Recent Multi-wavelength Campaign (2005)

Chakrabarti, Sandip K., Anandarao, B. G., Pal, S., Mondal, Soumen, Nandi, A., Bhattacharyya, A., ...

We conducted a multi-wavelength campaign in September-October, 2002, to observe SS 433. We used 45 meter sized 30 dishes of Giant Meter Radio Telescope (GMRT) for radio observation, 1.2 meter...

Results of Recent Multi-wavelength Campaign of SS433 (2005)

Pal, S., Chakrabarti, Sandip K., Goswami, K., Nandi, A., Rao, B. G. Ananda, Mondal, Soumen

We conducted multi wavelength campaign on SS433 in Sept. 2002 using X-ray, B, Infra-Red and radio telescopes. We observed variabilities on a time-scale of few minutes in all the wavelengths. We...

Possible Photometric Evidence of Ejection of Bullet Like Features in the Relativistic Jet source SS433 (2004)

Chakrabarti, Sandip K., Pal, S., Nandi, A., Anandarao, B. G., Mondal, Soumen

SS433 is well-known for its precessing twin jets having optical bullets inferred through {\it spectroscopic} observation of $H_\alpha$ lines. Recently, Chakrabarti et al. (2002) described processes...
