The K2 and TESS Synergy. III. Search and Rescue of the Lost Ephemeris for K2's First Planet

The Astronomical Journal
K2-2 b/HIP 116454 b, the first exoplanet discovery by K2 during its Two-Wheeled Concept Engineering Test, is a sub-Neptune (2.5 ± 0.1 R _⊕ , 9.7 ± 1.2 M _⊕ ) orbiting a relatively bright ( K _S = 8.03) K-dwarf star on a 9.1 day period. Unfortunately, due

Direct Evidence of Photochemistry in an Exoplanet Atmosphere

, 2022
Photochemistry is a fundamental process of planetary atmospheres that is integral to habitability, atmospheric composition and stability, and aerosol formation. However, no unambiguous photochemical products have been detected in exoplanet atmospheres to

From Underground Oceans to Continents: A Glimpse into the Water Inventory on Rocky Planets Using Host Star Abundances

The Astrophysical Journal
The amount of surface water is thought to be critical for a planet’s climate stability and thus habitability. However, the probability that a rocky planet may exhibit surface water at any point in its evolution is dependent on multiple factors, such as ...

MESSENGER Observations of a Possible Alfvén Wing at Mercury Driven by a Low Alfvénic Mach Number Interplanetary Coronal Mass Ejection

Journal of Geophysical Research: Space Physics, Volume 130, Issue 3, March 2025.
Abstract We investigate Mercury's response to rare, low Alfvénic Mach number MA $\left({M}_{A}\right)$ solar wind conditions using observations from the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) mission. This study provides compelling evidence of Mercury's altered magnetospheric state under these extreme conditions ...

White Dwarf Stars in the Big Data Era

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT White dwarf stars are the most common endpoint of stellar evolution. Therefore, these old, numerous and compact objects provide valuable information on the late stages of stellar evolution, the physics of dense plasma and the structure and evolution of our Galaxy.
