Searching for GEMS: TOI-5916 b & TOI-6158 b are Two Saturn-density Planets Orbiting M2 Dwarfs
The Astronomical JournalWe confirm the planetary nature of (1) TOI-5916 b and (2) TOI-6158 b, two giant exoplanets around M-dwarf stars (GEMS), both discovered by the Transiting Exoplanet Survey Satellite.

The Astronomical JournalGiant planets orbiting low-mass M dwarfs challenge current planet formation theories, which predict that such planets are unlikely to form. Characterizing their atmospheres can provide key insight into their origins, but analysis is complicated by ...

Two Extrasolar Planets from the Anglo‐Australian Planet Search
, 2002 We report the detection of two new extrasolar planets from the Anglo-Australian Planet Search around the stars HD 142 and HD 23079. The planet orbiting HD 142 has an orbital period of just under 1 yr, while that orbiting HD 23079 has a period of just ...

Searching for Planets Orbiting Vega with the James Webb Space Telescope
The Astronomical JournalThe most prominent of the IRAS debris disk systems, α Lyrae (Vega), at a distance of 7.7 pc, has been observed by both the NIRCam and MIRI instruments on the James Webb Space Telescope.

Polarization Spectra of Extrasolar Giant Planets
, 2004 We present simulated spectra of the flux and degree of polarization of starlight that is reflected by extrasolar giant planets (EGPs). In particular the polarization depends strongly on the structure of the planetary atmosphere, and appears to be a ...

The Evolution of Jupiter and Saturn as a Function of the Rρ Parameter
The Astrophysical JournalComputed using the APPLE planetary evolution code, we present updated evolutionary models for Jupiter and Saturn that incorporate helium rain, nonadiabatic thermal structures, and “fuzzy” extended heavy-element cores.

A Possible Mechanism to Explain the Prograde Equatorial Jet of a Jupiter-like Gaseous Giant
The Astrophysical Journal LettersGaseous giants are characterized by their deep atmospheres, which lack clear boundaries with their interiors; therefore, their internal states could directly influence atmospheric dynamics. So far, most modeling studies have considered deep convection as

The Astrophysical Journal LettersRecent observational constraints on the internal structure of Jupiter and Saturn suggest that these planets have “fuzzy” cores, i.e., gradients of the concentration of heavy elements that might span a large fraction of the planet’s radius.
