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.
In this paper, we report the discovery of two new super Li-rich K giants: HD 24960 and TYC 1751-1713-1. Based on high-resolution (R ≈ 60 000) spectroscopy, we have derived Li abundance of A(Li) ≈ 4.0 dex for both stars. Other elemental abundances are normal of typical...
We extend our modified parameter search method (Sridharan, Dashora, and Venkatakrishnan, Solar Phys.222, 35, 2004) of estimating the Fried parameter (r0) from long exposure images to the images obtained from the Hα-telescope installed at Merak, a cold desert on the Himalayas, with a...
The majority of the γ-ray sources detected by the Fermi Gamma-ray Space Telescope belong to the blazar class of active galactic nuclei (AGNs). In addition to blazars, a minority of non-blazar AGNs is also found to be γ-ray emitters. A class of AGNs with large jet to&...
Solar atmosphere is stratified and exhibits dynamic structures with confined hot plasmas. The corona consists of dynamic magnetic structures,in the form of closed and open loops with an enhanced plasma density . Moreover , these elastic and compressible structures s...
We present the colour and flux variability analysis at 3.4 μm (W1 band) and 4.6 μm (W2 band) of 492 narrow-line Seyfert 1 (NLSy1) galaxies using archival data from the Wide-field Infrared Survey Explorer (WISE). In the WISE colour–colour, (W1 − W2) versus (W2 − W3) d...
