Three small transiting planets around the M dwarf host star LP 358-499
, 2017 We report on the detection of three transiting small planets around the low-mass star LP 358-499 (K2-133), using photometric data from the Kepler-K2 mission. Using multiband photometry, we determine the host star to be an early M dwarf with an age likely

Beyond Earth: Resilience of Quasi‐2D Perovskite Solar Cells in Space
Advanced Materials, EarlyView.In the article (DOI: 10.1002/adma.202520433), Christoph Putz and co‐workers demonstrate rigid quasi‐2D perovskite solar cells operating in low Earth orbit, delivering stable power for more than 100 days under real‐space conditions. In‐orbit performance is correlated with extensive ground‐based thermal and proton‐irradiation studies on rigid and ...

Dusty Outflows in Planetary Atmospheres: Understanding “Super-puffs” and Transmission Spectra of Sub-Neptunes [PDF]
Astrophysical Journal, 2019 “Super-puffs” are planets with anomalously low mean densities ( ). With a low surface gravity, the extended atmosphere is susceptible to extreme hydrodynamic mass loss (“boil-off”) on a timescale that is much shorter than the system’s age.
