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…
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…
Characterizing the Galactic and Extragalactic Background Near Exoplanet Direct Imaging Targets
M. Cracraft, R. J. De Rosa, W. Sparks +2
As more missions attempt to directly image and characterize exoplanets orbiting nearby sun-like stars, advance characterization of possible contaminating background sources becomes…
Active Cryovolcanism on Europa?
William B. Sparks, Britney E. Schmidt, Melissa A. McGrath +4
Evidence for plumes of water on Europa has previously been found using the Hubble Space Telescope (HST) using two different observing techniques. Roth et al. (2014) found line emis…
Probing for Evidence of Plumes on Europa with HST/STIS
W. B. Sparks, K. P. Hand, M. A. McGrath +3
Roth et al (2014a) reported evidence for plumes of water venting from a southern high latitude region on Europa - spectroscopic detection of off-limb line emission from the dissoci…
