Long-lived revivals and real-space fragmentation in chains of multispecies Rydberg atoms

Posted by klaurent Delft

Kavli Affiliate: Natalia Chepiga | Summary:Arrays of Rydberg atoms provide a powerful platform for exploring constrained quantum dynamics and nonergodic many-body phenomena. While most work has focused on single-species systems, multispecies architectures offer additional interaction channels and enable new forms of dynamical constraints. We study the nonequilibrium dynamics of one-dimensional dual-species Rydberg chains of Cs […]

How I Wonder What You Are — JWST’s Little Red Dots do not TWINKLE

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | Summary:Little Red Dots (LRDs) are a population of compact, red sources that have emerged as one of the most puzzling findings of JWST. Variability provides a direct probe of their central engines. Here we present the first joint spectroscopic and photometric time-domain study of LRDs undertaken with the JWST TWINKLE […]

The $R$-Process Alliance: Actinide Abundances, Variation, and Evolution in Metal-Poor Stars

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | Summary:The actinides, including thorium (Th), are the heaviest observable elements synthesized in the universe, holding clues to the extremes of the astrophysical and nuclear conditions of $r$-process sites. We present Th abundances based on high-resolution spectroscopy for 47 metal-poor stars, the largest homogeneously analyzed sample to date. The chemical evolution […]

Variability classification of TESS targets in LOPS2, the first long-term pointing field of PLATO. Version 1 of the public variability catalogue

Posted by klaurent MIT

Kavli Affiliate: George Ricker | Summary:The PLAnetary Transits and Oscillations of stars (PLATO) mission is expected to launch in January 2027. A total of 8% of its data rate will be dedicated to complementary science targets selected from approved Guest Observer proposals. We seek to provide an open-source catalogue of variable stars in PLATO’s first […]

JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation

Posted by klaurent Peking

Kavli Affiliate: Feng Long| Summary: We present JWST/MIRI-MRS observations of ISO-Oph 37, a highly inclined flat-spectrum ($lesssim$1 Myr old) source, to investigate the chemical composition and dynamical origin of its inner-disk gas. The spectrum reveals a rich combination of molecular emission and absorption: H$_2$O, CO, and OH are detected in emission, while strong absorption is […]
