A possible solution for the faint young Sun paradox: Clues from the exoplanetary data

Shashanka R. Gurumath, K. M. Hiremath, V. Ramasubramanian +1

Faint young Sun paradox (FYSP) is one of the unsolved problem in solar physics. The present study aims to get a possible solution for the FYSP through sun-like G stars and their ex…

Forecast and backcast of the solar cycles

K M Hiremath

Solar cycle is modeled as a forced and damped harmonic oscillator and the amplitudes, frequencies, phases and decay factors of such a harmonic oscillator are estimated by non-linea…

Rotation rate of high latitude and near polar coronal holes

K. M. Hiremath, Manjunath Hegde, K. R. Varsha

For the period of 1997-2006, coronal holes detected in the SOHO/EIT 195 full disk calibrated images are used to compute the rotation rates of high latitude and near polar coron…

Thermal and magnetic field structure of near equatorial coronal holes

K. M. Hiremath, Manjunath Hegde

We use full-disk, SOHO/EIT 195 calibrated images to measure latitudinal and day to day variations of area and average photon fluxes of the near equatorial coronal holes. In add…

Nearly Century-scale Variation of the Sun's Radius

K. M. Hiremath, J. P. Rozelot, V. Sarp +3

The Kodaikanal Archive Program (India) is now available to the scientific community in digital form as daily digitized solar white light pictures, from 1923 to 2011. We present her…

Kodaikanal calcium images: Detection of plages, Fixing the heliographic coordinates and Estimation of Area

K. M. Hiremath, Shreyam Krishna, Adithya H. N +2

Kodaikanal Observatory is a veritable treasure trove of data, with the data repository covering almost 100 years of observations. For the years 1909-2007, we use calibrated Ca II K…
