Transmission Spectrum of the Benchmark Temperate Exo-Neptune TOI-1231 b

Subhajit Sarkar, Nikku Madhusudhan, Lorenzo Pica-Ciamarra +4

The JWST is revolutionizing our understanding of the temperate sub-Neptune population through atmospheric spectroscopy. The nature of these planets remains debated, as their bulk p…

The Mid-Infrared Transmission Spectrum of the Temperate Sub-Neptune TOI-270 d

MÃ¥ns Holmberg, Nikku Madhusudhan, Martin Binet +3

Observations of temperate sub-Neptunes with JWST have ushered in a new era for atmospheric characterization of small exoplanets. In particular, the MIRI instrument provides a uniqu…

Hot Rocks Survey V: Secondary Eclipse Photometry of GJ 3473 b with JWST/MIRI

Måns Holmberg, Hannah Diamond-Lowe, João M. Mendonça +16

JWST is transforming our ability to characterise small exoplanets, from sub-Neptunes to rocky worlds. A key open question is whether highly irradiated rocky planets can retain atmo…

A JWST Transmission Spectrum of the Temperate Sub-Neptune TOI-732 c

Frances E. Rigby, Nikku Madhusudhan, Subhajit Sarkar +3

In recent years, JWST has facilitated detections of carbon-bearing molecules in the atmospheres of temperate sub-Neptunes orbiting M dwarfs, ushering in a new era in the characteri…

The atmospheric composition of TOI-270 d

Savvas Constantinou, Nikku Madhusudhan, MÃ¥ns Holmberg

The first explorations of temperate sub-Neptune exoplanets have been the hallmark of early JWST observations. The bulk properties of such planets are consistent with a range of pos…

Exploring the Sub-Neptune Frontier with JWST

Nikku Madhusudhan, MÃ¥ns Holmberg, Savvas Constantinou +1

Sub-Neptune planets, with sizes and masses between those of Earth and Neptune, dominate the exoplanet population. Sub-Neptunes are expected to be the most diverse family of the exo…
