A dense mini-Neptune orbiting the bright young star HD 18599
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT Very little is known about the young planet population because the detection of small planets orbiting young stars is obscured by the effects of stellar activity and fast rotation, which mask planets within radial velocity and transit data sets.

The Astrophysical Journal Letters, 2023 We report the discovery of two TESS sub-Neptunes orbiting the early M dwarf TOI-904 (TIC 261257684). Both exoplanets, TOI-904 b and c, were initially observed in TESS Sector 12 with twin sizes of ${2.426}_{-0.157}^{+0.163}$ and ${2.167}_{-0.118}^{+0.130}$

Plant Biology, Volume 25, Issue 7, Page 1121-1141, December 2023., 2023 Ectopic expression of the AtOTS1 SUMO protease enhances drought tolerance in sugarcane by protecting the photosynthetic machinery and membrane integrity, and decreasing SUMOylation and protease activity. ABSTRACT Sugarcane is an economically important crop plant across the globe as it is the primary source of sugar and biofuel.

Detection of Ongoing Mass Loss from HD 63433c, a Young Mini-Neptune
The Astronomical Journal, 2022 Abstract We detect Lyα absorption from the escaping atmosphere of HD 63433c, a R = 2.67R ⊕, P = 20.5 day mini-Neptune orbiting a young (440 Myr) solar analog in the Ursa Major Moving Group. Using Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph, we measure a transit depth of 11.1 ± 1.5% in the blue wing

Human Psychopharmacology: Clinical and Experimental, Volume 38, Issue 6, November 2023., 2023 Abstract Objective It is unclear how healthcare professionals (HCPs) experience and view the challenges of working with people who use New Psychoactive Substances (PWUNPS), in different healthcare services (HCS). The aim of the study was to explore HCPs' experiences of working with individuals who use NPS across statutory, non‐statutory, and private ...

On the Temperature Profiles and Emission Spectra of Mini-Neptune Atmospheres [PDF]
The Astrophysical Journal, 2020 Abstract Atmospheric observations of mini-Neptunes orbiting M dwarfs are beginning to provide constraints on their chemical and thermal properties, while also providing clues about their interiors and potential surfaces. With their relatively large scale heights and large planet–star contrasts, mini-Neptunes are currently ideal targets ...

Atmospheric Circulation and Composition of GJ1214b [PDF]
, 2011 The exoplanet GJ1214b presents an interesting example of compositional degeneracy for low-mass planets. Its atmosphere may be composed of water, super-solar or solar metallicity material.

TOI-712: A System of Adolescent Mini-Neptunes Extending to the Habitable Zone [PDF]
The Astronomical Journal, 2022 Abstract As an all-sky survey, NASA’s Transiting Exoplanet Survey Satellite (TESS) mission is able to detect the brightest and rarest types of transiting planetary systems, including young planets that enable study of the evolutionary processes that occur within the first billion years.

Deuterium Escape on Photoevaporating Sub-Neptunes
The Astrophysical Journal Letters, 2023 We investigate the evolution of the deuterium-to-hydrogen (D/H) mass ratio driven by EUV photoevaporation of hydrogen-rich atmospheres of close-in sub-Neptunes around solar-type stars.
