Detached cold dust shell around the early R star (warm carbon star) HD 100764

Parthasarathy, M (The European Southern Observatory, 1991-07)

The existence of a dust shell and warm dust near HD 100764 are determined from IRAS observations of early R stars, and the ramifications of the findings are discussed. The mass of the dust shell is calculated to be 0.510 ...
Further VLA observations of hydrogen deficient stars

Kameswara Rao, N; Venugopal, V. R; Patnaik, A. R (Indian Academy of Sciences, 1987-09)

VLA observations at 6 cm have been obtained for three hydrogen-deficient objects (Upsilon Sgr, V 348 Sgr, and Abell 58). Abell 58 was also observed at 2 cm. Only upper limits to the flux density could be set for these ...
Late time X-ray, IR and radio observations of the tidal disruption event galaxy NGC 5905

Raichur, H; Mousumi Das; Herrero, A. A; Shastri, P; Kantharia, N. G (Springer, 2015-04)

NGC 5905 is one of the few galaxies with no prior evidence for an active galactic nucleus (AGN) in which an X-ray flare was detected by the ROSAT All Sky Survey (RASS) in 1990–1991. Follow-up studies showed that the X-ray ...
Near infrared observations of the solar atmosphere

Prasad, C. D (Astronomical Society of India, 1998)

Due to the availability of the advanced two dimensional array detectors for detecting the near infrared (IR) wavelength, it has become possible to study new aspects of solar atmosphere during the recent times. The main ...
