• Accretion Disk-Corona connection in Active Galactic Nuclei 

  Pal, Indrani (Indian Institute of Astrophysics, 2023-05)

  Active Galactic Nuclei (AGN), amongst the most luminous sources in the Universe (L = 1042 − 1046 erg s −1 ), emit radiation over the entire electromagnetic band. Though AGN are known to be powered by the accretion of matter ...
• Unravelling the nature of explosion of thermonuclear supernovae 

  Dutta, Anirban (Indian Institute of Astrophysics, 2023-05)

  Type Ia supernovae (SNe Ia) result from thermonuclear explosions in binary systems consisting of at least one carbon-oxygen white dwarf. They are crucial for the understanding of galactic chemical composition as they are ...
• High precision spectroscopy using stabilized Fabry-Perot Etalon 

  Das, Tanya (Indian Institute of Astrophysics, 2021)

  Accurate wavelength calibration is an important factor for any measure ment with high resolution spectrographs. Stellar spectrum comprises of dis crete absorption or emission lines whose position is precisely determined ...
• Investigating the ultra-violet bright stars in star clusters 

  Rani, Sharmila (Indian Institute of Astrophysics, 2023-02)

  Star clusters are gravitationally bound systems composed of a large number of stars, ranging from thousands to millions. As the dynamic age of the cluster is less than the age of the universe, dynamical interactions ...
• Characterization of the Atmosphere of Extrasolar Planets 

  Sengupta, Soumya (Indian Institute of Astrophysics, 2022-05)

  Context: Starting from the first discovery of extrasolar planet or exoplanet around a sun-like star, more than 5,000 confirmed exoplanets have been detected till now. But still we have very less information and interpretations ...
• Kinematics of Coronal Mass Ejections in the Inner Corona and its Coupling with the Heliosphere 

  Majumdar, Satabdwa (Indian Institute of Astrophysics, 2022-07)

  Ever since the dawn of astronomy, we and the Sun have not been celestial strangers anymore, and it was soon realised that there is a close Sun-Earth connection that was awaiting our acknowledgement. With that came several ...
• Precise Transit Photometric Studies of Exoplanets and Exomoons 

  Saha, Suman (Indian Institute of Astrophysics, 2022-09)

  The most challenging limitation in the transit photometry method arises from the noises in the photometric signal. In particular, the ground-based telescopes are heavily affected by the noise due to the perturbation in ...
