Atmospheric escape from exoplanets: recent observations and theoretical models [PDF]
The review aims to give an overview of atmospheric escape processes from exoplanets. I briefly discuss the physics of various escape processes responsible for atmospheric escape across different types of exoplanets. Transmission spectroscopy is one of the major workhorses to observe the escaping atmosphere from exoplanets. I discuss recent observations

WASP-69b’s Escaping Envelope Is Confined to a Tail Extending at Least 7 Rp
Studying the escaping atmospheres of highly irradiated exoplanets is critical for understanding the physical mechanisms that shape the demographics of close-in planets.

The Impact-driven Atmospheric Loss of Super-Earths around Different Spectral Types of Host Stars
A planet’s mass loss is important for the its formation and evolution. The radius valley (RV) is believed to be triggered by evaporation-induced mass loss.

Terrestrial planets currently in the habitable zone around M dwarfs are estimated to have been in runaway greenhouse conditions for up to ∼1 Gyr due to the long-term pre-main-sequence phase of M dwarfs.

The Formation of Double Hot Jupiter Systems through von Zeipel–Lidov–Kozai Migration
The von Zeipel–Lidov–Kozai (ZLK) mechanism with tidal friction has been demonstrated as a promising avenue to generate hot Jupiters in stellar binary systems.

Separating Super-puffs versus Hot Jupiters among Young Puffy Planets
Discoveries of close-in young puffy ( R _p ≳ 6 R _⊕ ) planets raise the question of whether they are bona fide hot Jupiters or puffed-up Neptunes, potentially placing constraints on the formation location and timescale of hot Jupiters.

Observational Signatures of a Previous Dynamical Instability in Multi-planet M-dwarf Systems
We identify observational signatures suggesting a history of dynamical instability in 26 out of 34 M-dwarf multi-planet systems containing no large planets.
