JWST-DECO: Temporal Variations in the Mid-IR Silicate Features of Two T Tauri Discs Based on Spitzer and JWST observations
N. Sameshima, T. Miyata, T. Kamizuka +9
Mid-infrared spectra of planet-forming discs commonly show prominent silicate emission, whose spectral shape is sensitive to the disc temperature distribution as well as its minera…

A Protoplanet Candidate in the PDS 66 Disk Indicated by Silicon Sulfide Isotopologues
Tomohiro C. Yoshida, Felipe Alarcón, Jaehan Bae +11
Despite observational progress in planet formation, the stage in which planetesimals grow into planets remains poorly understood. During this phase, protoplanets may develop gaseou…

Tracing Quenching in Nearby Galaxies Through Inner Surface Mass Density and Cold Gas Content
Evangela E. Shread, Trevor J. Weiss, Jerome J. Fang +1
The inner stellar mass surface density within 1 kpc, Sigma1, has emerged as a suitable proxy for bulge growth and galaxy quenching. However, the dependence of cold gas content on S…
