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.
We present an estimation of the electron density modulation index (δNe/Ne) for the first time using solar type IIIb radio burst observations. The mean value of δNe/Ne is calculated to be ≈0.006±0.002 over the heliocentric distance range r≈1.6--2.2 R⊙. The estimated δNe/Ne ...
We estimated the coronal magnetic field strength (B) during the 23 July 2016 coronal mass ejection (CME) event using i) the flux rope structure of the CME in the white-light coronagraph images and ii) the band-splitting in the associated type II burst. No models were assu...
We report the beginning of activity for comet C/2015 ER61 (PANSTARRS), the first instance of watching a long-period comet turn on. Pre-discovery observations and observations from the NEOWISE space telescope suggest that the nucleus is large, with a radius of R N ~ 9...
Carbon-enhanced metal-poor (CEMP) stars bear important imprints of the early chemical enrichment of any stellar system. While these stars are known to exist in copious amounts in the Milky Way halo, detailed chemical abundance data from the faint dwarf spheroidal (dSph) satellites are...
The Sun is a unique physical laboratory in which the various domains of physics inaccessible to laboratories on earth can be studied in great detail. Its proximity allows us to understand it in great depths. George Ellery Hale, in 1908, discovered the magnetic fields...
