A JWST/MIRI Aanalysis Of The Ice Distribution And PAH Emission In The Protoplanetary Disk HH 48 NE
Ice-coated dust grains provide the main reservoir of volatiles that play an important role in planet formation processes and may become incorporated into planetary atmospheres.

Webb Images Cold Exoplanet Epsilon Indi Ab 12 Light-Years Away
If alien astronomers in a nearby star system had a telescope like NASA’s James Webb Space Telescope, and they pointed it toward our solar system, then Jupiter might look very […]

Observational Characteristics Of Circum-planetary-mass-object Disks In The Era Of James Webb Space Telescope
Recent observations have confirmed circumplanetary disks (CPDs) embedded in parental protoplanetary disks (PPDs). On the other hand, planetary-mass companions (PMCs) and planetary-mass objects (PMOs) are likely to harbor their own […]

Debris Disks can Contaminate Mid-Infrared Exoplanet Spectra: Evidence for a Circumstellar Debris Disk around Exoplanet Host WASP-39
The signal from a transiting planet can be diluted by astrophysical contamination. In the case of circumstellar debris disks, this contamination could start in the mid-infrared and vary as a […]

Planet-forming Disks Around Very Low-mass Stars Are Different
Planets form in disks of gas and dust, orbiting young stars. The MIRI Mid-INfrared Disk Survey (MINDS), led by Thomas Henning from the Max Planck Institute for Astronomy (MPIA) in […]

Reconnaissance Of Potentially Habitable Worlds With Webb Space Telescope
Exoplanets are common in our galaxy, and some even orbit in the so-called habitable zone of their star. NASA’s James Webb Space Telescope has been busy observing a few of […]

JWST-TST High Contrast: JWST/NIRCam Observations Of The Young Giant Planet β Pic b
We present the first JWST/NIRCam observations of the directly-imaged gas giant exoplanet β Pic b. Observations in six filters using NIRCam’s round coronagraphic masks provide a high signal-to-noise detection of […]

A High Internal Heat Flux and Large Core in a Warm Neptune Exoplanet
Interactions between exoplanetary atmospheres and internal properties have long been hypothesized to be drivers of the inflation mechanisms of gaseous planets and apparent atmospheric chemical disequilibrium conditions.
