A second visit to Eps Ind Ab with JWST: new photometry confirms ammonia and suggests thick clouds in the exoplanet atmosphere of the closest super-Jupiter
Elisabeth C. Matthews, James Mang, Aarynn L. Carter +9
With JWST, we are directly imaging cold (~200-300K), solar-age giant exoplanets for the first time. At these temperatures many molecular features appear and water-ice clouds may co…

A temperate super-Jupiter imaged with JWST in the mid-infrared
E. C. Matthews, A. L. Carter, P. Pathak +16
Of the ~25 directly imaged planets to date, all are younger than 500Myr and all but 6 are younger than 100Myr. Eps Ind A (HD209100, HIP108870) is a K5V star of roughly solar age (r…

TOI-1685 b is a Hot Rocky Super-Earth: Updates to the Stellar and Planet Parameters of a Popular JWST Cycle 2 Target
Jennifer A. Burt, Matthew J. Hooton, Eric E. Mamajek +12
We present an updated characterization of the TOI-1685 planetary system, which consists of a P = 0.69\,day USP super-Earth planet orbiting a nearby ( = 37.6\,pc) M2.5…
