Asteroseismology<\/strong><\/p>\n

Asteroseismology allows an unprecedented way to determine the internal structure of stars by studying their oscillations. Recent efforts have been performed allowing the detection of many frequencies in different kinds of pulsating stars. The pulsation is caused by stellar oscillations in three orthogonal directions, radial distance, co-latitude and longitude of the stellar structure. The result is radial and non-radial oscillation modes.<\/p>\n

My research is mainly focused on the pulsation analysis of short period variable stars. These short period variable stars are called Delta Scuti type stars. The radial and non-radial modes are determined using the photometric and spectroscopic observations of Delta Scuti stars and hence find the internal properties of the stars.\u00a0 For more information please read my PhD thesis<\/a>.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Observation of Solar Radio Bursts using CALLISTO<\/strong><\/p>\n

The Compact Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory (CALLISTO) radio spectrometer observes radio emissions solar flares. The instruments observe automatically, and data is collected every day via internet and stored in a central data base. A public web interface exists through which data can be browsed and retrieved. The e-CALLISTO system has already proven to be a valuable new tool for monitoring solar activity and for space weather research.<\/p>\n

The CALLISTO radio spectrometer was donated by the Institute of Astronomy, Switzerland and Log-Periodic antenna was built and installed the system at the Arthur C Clarke Institute. See more details: https:\/\/www.e-callisto.org\/<\/a><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
