The Role Of The Hubble Space Telescope In Advancing Our Understanding Of Atmospheric Escape In Exoplanets
An important evolutionary pathway for planetary atmospheres is escape to space, which has been studied on Earth and Mars for several decades and more recently in exoplanets.

Simulation Of The Spin Evolution Of Some Selected Exoplanets And Inferences On Their Climate
In this work, using the simulator VPLanet, we analyze the spin evolution of some selected exoplanets due to the tidal interaction with their host star.

When Tropical Oceans On Earth Were Oxygen Oases
The tropical oceans that once served as oxygen-rich havens for Earth’s earliest complex life have become the planet’s largest marine dead zones. The dramatic reversal occurred hundreds of millions of […]
