Abstract:
The exoplanetary population has grown since 1995 from one to over 7,400. Complicated detection methods are necessary due to exoplanets’ faintness and proximity to host stars. Using space telescopes, along with ground-based observations and transmission spectroscopy, the field has advanced astronomically over three decades. Exoplanets differ from solar system planets in mass, radius, temperature, and atmosphere composition. Observed trends reveal exotic planetary architecture: "peas in a pod," “radius valley”, "hot-Neptunes desert." Stellar properties appear to play a crucial role in shaping planetary systems and affecting the likelihood for life to emerge. The Centre for Planetary Habitability (PHAB) at UiO, first in Norway, investigates planet habitability, aiming to identify key conditions and recognise potentially habitable exoplanets.
Biography:
Elena Mamonova is PhD fellow at the Centre for Planetary Habitability (PHAB), University of Oslo. She graduated from the Lomonosov Moscow State University, Department of Physics and got a second bachelor’s degree there at the Department of Journalism. She had her Master’s degree in Geophysics, Geodynamics and Planetary Sciences at the Department of Mathematics and Natural Sciences, University of Oslo. Her research is focused on studying terrestrial planets orbiting other stars than the Sun, specifically exoplanets atmospheres exposed to harsh stellar environments of actively flaring low-mass stars.
