hot-Neptune desert Archives

A section of the Rp versus Mp linear-log diagram of known transiting exoplanets with a mass between 10 and 100 M⊕ (measured with an accuracy to within 20%) and a radius between 3 and 10 R⊕. Data taken from TEPCat. The positions of TOI-1274 b and TOI-1694 b are highlighted (this work). Exoplanets inside the green zone are giant planets with sizes and masses between those of Neptune and Saturn. The position of Uranus, Neptune, and Saturn are also marked with red capital letters. -- astro-ph.EP

The GAPS Programme at TNG LXXIV. A Reanalysis Of The Planetary Systems TOI-1272 And TOI-1694 With HARPS-N And Retraction Of The Planetary Interpretation Of TOI-1272 c

[astro-ph.EP] Hot Neptunes are close-in exoplanets that occupy a sparsely populated region of parameter space known as the “hot-Neptune desert”.

Surface electrostatic maps of adenylate kinase (Adk), β-galactosidase (β-Gal), DNA ligase (LigA), glycerol kinase (GlpK), histidinol-phosphate aminotransferase (HisC), malate dehydrogenase (MDH) and signal recognition particle 54 (SRP54) are shown for Escherichia coli (mesophile), Psychromonas ingrahamii (psychrophile), Haloferax volcanii (halophile), and Halorubrum lacusprofundi (psychrohalophile). Electrostatic potentials were calculated from predicted structures and mapped onto the molecular surface. Blue indicates positive electrostatic potential and red indicates negative electrostatic potential. -- Frontiers in Microbiology

Introduction – Cryo-hypersaline brines combine sub-zero temperatures with near-saturated salinity, creating one of Earth’s most extreme habitats. Antarctic Deep Lake provides a natural model for studying how proteins remain stable […]
