Metal Polluted White Dwarfs with 21 μm IR excesses from JWST/MIRI: Planets or Dust?
John H. Debes, Sabrina Poulsen, Ashley Messier +13
White dwarfs with metal pollution are caused by the accretion of rocky dust from tidally disrupted minor bodies and are signposts for planetary systems. These minor bodies are pert…
The JWST/NIRISS Deep Spectroscopic Survey for Young Brown Dwarfs and Free-Floating Planets
Adam B. Langeveld, Aleks Scholz, Koraljka Mužić +9
The discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. Here we report results from an…
Transmission Spectroscopy of the Habitable Zone Exoplanet LHS 1140 b with JWST/NIRISS
Charles Cadieux, René Doyon, Ryan J. MacDonald +20
LHS 1140 b is the second-closest temperate transiting planet to the Earth with an equilibrium temperature low enough to support surface liquid water. At 1.7300.025 R,…
JWST Directly Images Giant Planet Candidates Around Two Metal-Polluted White Dwarf Stars
Susan E. Mullally, John Debes, Misty Cracraft +9
We report the discovery of two directly imaged, giant planet candidates orbiting the metal-rich DAZ white dwarfs WD 1202-232 and WD 2105-82. JWST's Mid-Infrared Instrument (MIRI) d…
A MIRI Search for Planets and Dust Around WD 2149+02
Sabrina Poulsen, John Debes, Misty Cracraft +9
The launch of JWST has ushered in a new era of high precision infrared astronomy, allowing us to probe nearby white dwarfs for cold dust, exoplanets, and tidally heated exomoons. W…
