Welcome to the Digital Repository of Indian Institute of Astrophysics
This digital repository of Indian Institute of Astrophysics (IIAP), Bangalore, India is developed to capture, organize disseminate and preserve the research publications of IIAP. It also includes the in-house technical reports and annual reports in addition to various other grey literatures created within the institute.You can search, browse and access full text of these publications from the repository.
This Repository also hosts papers published in Bulletin of the Astronomical Society of India, Volumes 1 to 33, 1973 to 2005. The contents of Vol. 34, 2006 to Current can be accessed from the BASI HOMEPAGE
Archival Collection in Open Access
Indian Institute of Astrophysics traces its origin back to 1786, and the Institute has naturally inherited the library and records of the Madras and Kodaikanal Observatories. This collection of archival records has grown over the years in various formats such as manuscripts, photographs, maps, films, awards, hand-drawn sketches, pictures and instruments.
Supernovae (SNe) are explosive transient events thatmark the end stage of stellar evolution. This work presents a study of low redshift, hydrogen deficient (Type I) SNe, with emphasis on SNe of type Ia. The data were primarily obtained from the 2-metre Himalayan Chandra Telescope...
Using our previously reported observations, we derive some physical parameters of the moderately fast nova V2676 Oph 2012 #1. The best-fit Cloudy model of the nebular spectrum obtained on 2015 May 8 shows a hot white dwarf source with TBB≈1.0×105 K having a luminosity of ...
Energetic emission from the Sun can be divided into two broad categories, viz. gradual and impulsive. It is inferred from white-light observations that the first group is associated with mass ejections from the solar corona (i.e., coronal mass ejections or CMEs) whereas the second&...
It is often noticed that the occurrence rate of Coronal Mass Ejections (CMEs) increases with increase in flare duration where peak flux too increase. However, there is no complete association between the duration and peak flux. Distinct characteristics have been reported for active ...
Flare characteristics such as the flare occurrence number density and the distribution of peak flux as well as duration of flares occurring on either side of a coronal mass ejection (CME) onset time are studied. While the flares are rather evenly distributed statistically on e...
