Star Planet Interactions
Arghyadeep Paul, Kristina Kislyakova, Manuel Güdel +13
Star-planet interactions (SPIs) describe the continuous exchange of energy, momentum, and mass between exoplanets and their host stars through radiative, tidal, magnetic, and parti…
Star-Planet Interactions: The Instrumentation Perspective
H. Korhonen, P. Figueira, B. Montet +4
Star-Planet Interactions (SPIs) produce observable phenomena across the electromagnetic spectrum, from X-ray and ultraviolet emission tracing magnetic activity and atmospheric esca…
Correlation Between Lunar Surface and Exospheric Sodium: Effects of Albedo-Driven Temperature on Multilayer Sodium Reservoirs Rather Than Surface Abundance Variations
A. Devaraj, S. Narendranath, Sreeja. S. Kartha +1
Sodium (Na) is a moderately volatile element in the lunar exosphere, released from the surface through thermal and non-thermal processes. We present a combined analysis of Chandray…
Non-Linear Solar EUV-Driven Sodium Release from the Lunar Surface: A Contrast to the Linear PSD Model
A Devaraj, S Narendranath, Sreeja S Kartha +7
The correlation between solar Extreme Ultra-Violet (EUV) radiation above 8.8 eV and the release of sodium from the lunar surface via photon-stimulated desorption (PSD) is investiga…
Lunar geochemistry from X-ray line flux ratios using CLASS on Chandrayaan 2
R. Kumar, Y. Rai, S. Srijan +13
Global lunar chemical maps are essential for understanding the origin and evolution of the Moon, its surface characteristics, and its potential for resource extraction. Lunar eleme…
