Probing the Atmospheres of Young Long-Period Sub-Neptune Progenitors with ELT/ANDES

Spandan Dash, Dwaipayan Dubey, Liton Majumdar

High-resolution cross-correlation spectroscopy (HRCCS) has become a powerful ground-based technique for detecting and characterizing exoplanet atmospheres. While highly successful…

Detectability of oxygen fugacity regimes in the magma ocean world 55 Cancri e at high spectral resolution

Spandan Dash, Matteo Brogi, Fabian Lukas Seidler +5

Ultra-short Period exoplanets (USPs) like 55 Cnc e, hosting dayside magma oceans, present unique opportunities to study surface-atmosphere interactions. The composition of a vapori…

Constraints on atmospheric water abundance and cloud deck pressure in the warm Neptune GJ 3470 b via CARMENES transmission spectroscopy

Spandan Dash, Matteo Brogi, Siddharth Gandhi +4

Observations of cooler atmospheres of super-Earths and Neptune sized objects often show flat transmission spectra. The most likely cause of this trend is the presence of aerosols (…

Linking atmospheric chemistry of the hot Jupiter HD 209458b to its formation location through infrared transmission and emission spectra

Spandan Dash, Liton Majumdar, Karen Willacy +6

The elemental ratios of carbon, nitrogen, and oxygen in the atmospheres of hot Jupiters may hold clues to their formation locations in the protostellar disc. In this work, we adopt…

Planet formation and disk mass dependence in a pebble-driven scenario for low mass stars

Spandan Dash, Yamila Miguel

Measured disk masses seem to be too low to form the observed population of planetary systems. In this context, we develop a population synthesis code in the pebble accretion scenar…

Atmospheric mass loss of extrasolar planets orbiting magnetically active host stars

Lalitha Sairam, J. H. M. M. Schmitt, Spandan Dash

Magnetic stellar activity of exoplanet hosts can lead to the production of large amounts of high-energy emission, which irradiates extrasolar planets, located in the immediate vici…
