Unveiling Metal Mixing in a Grand-Design Spiral: A UV-optical multiphase spatially resolved study of M83

Adarsh Ranjan, Bethan L. James, Svea Hernandez +4

We present a spatially resolved, multiphase study of chemical enrichment around young star clusters (YSCs) in the nearby grand-design spiral M83 by combining far-ultraviolet(UV) ab…

Observation of an Accreting Planetary-Mass Companion with Signs of Disk-Disk Interaction in Orion

Emilie Vila, Paul Amiot, Olivier Berné +11

Young ( Myr) planetary-mass companions (PMCs) provide valuable insights into the formation and early evolution of planetary systems. To date, only a dozen such objects…

First detection of ices in intermediate-mass young stellar objects beyond the Milky Way

Guido De Marchi, Nolan Habel, Margaret Meixner +15

Using NIRSpec on JWST, we studied a sample of 15 intermediate-mass (1.8-4.1 Msun) young stellar objects (YSOs) previously identified with MIRI photometry in the low-metallicity NGC…

Detection of a Deeply Embedded Protocluster Candidate in NGC 602 with JWST

Beena Meena, Peter Zeidler, Elena Sabbi +3

JWST NIRCam and MIRI photometry of NGC 602, a low-metallicity young star cluster in the Small Magellanic Cloud, reveals an extended mid-infrared bright emission feature designated…

XUE. JWST spectroscopy of externally irradiated disks around young intermediate-mass stars

María Claudia Ramírez-Tannus, Arjan Bik, Konstantin V. Getman +17

Most young stars and therefore planetary systems form in high-mass star forming regions and are exposed to ultraviolet radiation, affecting the protoplanetary disk. These regions a…

XUE 10. The CO2-rich terrestrial planet-forming region of an externally irradiated Herbig disk

Jenny Frediani, Arjan Bik, María Claudia Ramírez-Tannus +18

We investigate the James Webb Space Telescope (JWST) MIRI MRS gas molecular content of an externally irradiated Herbig disk, the F-type XUE 10 source, in the context of the eXtreme…
