The environmental imprint on molecular layering in the dusty streamer of M512
M. De Simone, L. Cacciapuoti, D. Capela +7
Protostellar streamers are elongated structures that channel material from larger scale onto disks, influencing their physical and chemical evolution. The M512 protostar in Orion/L…
Large Dust Grains and a Possible Dust Trap in the Polar Circumbinary Disc of HD 98800B
Ãlvaro Ribas, Thomas Lack, Francesco Zagaria +6
HD 98800 is a nearby hierarchical quadruple system comprising two binaries orbiting each other. Surprisingly, despite its 10 Myr age and dynamic environment, the Ba-Bb compo…
Indications of Rapid Dust Formation in the Inner Region of a Protoplanetary Disk
Thanawuth Thanathibodee, Catherine Espaillat, Nuria Calvet +4
We report a significant increase in mid-infrared emission m in a transitional disk. The 2024 JWST/MIRI observation of the disk around CVSO 1942 reveals flux increase b…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Isotopic Ratios in the Disk of HD 163296
Chunhua Qi, David J. Wilner, Catherine C. Espaillat
Isotopic abundance ratios in protoplanetary disks are critical for understanding volatile inheritance and chemical evolution in planet-forming environments. We present Atacama Larg…
IPA. Accretion rate of a low-mass Class 0 protostar, measured via mid-infrared fluorescent OH emission
Dan M. Watson, Mayank Narang, Caeley V. Pittman +41
The earliest stages of star formation are highlighted by complex interactions between accretion, outflow, and radiative processes, which shape the chemical and physical environment…
