The Age and High Energy Environment of the Very Young Transiting Exoplanet TOI 1227b
Attila Varga, Joel H. Kastner, Alexander S. Binks +2
The mid-M star TOI~1227 hosts among the youngest known transiting exoplanets. We have conducted new X-ray imaging and optical spectroscopic observations of TOI 1227 aimed at ascert…
Walking the Line: Young Stars on the Boundary of the Epsilon Cha and Lower Centaurus-Crux Associations
Attila Varga, Joel H. Kastner, D. Annie Dickson-Vandervelde +1
Gaia Data Release 3 (DR3) has provided the largest and most astrometrically precise catalogue of nearby stars to date, allowing for a more complete membership census of nearby, you…
Asymptotic giant branch stars in the eROSITA-DE eRASS1 catalog
Martin A. Guerrero, Rodolfo Montez, Roberto Ortiz +2
AGB stars are not expected to be X-ray-emitters, yet a small fraction of them, the so-called X-AGBs, show X-ray emission that can be attributed to coronal activity of a companion o…
The Molecular Exoskeleton of the Ring-like Planetary Nebula NGC 3132
Joel H. Kastner, David Wilner, Paula Moraga Baez +4
We present Submillimeter Array (SMA) mapping of CO , CO , and CN emission from the Ring-like planetary nebula (…
Twenty-Five Years of Accretion onto the Classical T Tauri Star TW Hya
Gregory J. Herczeg, Yuguang Chen, Jean-Francois Donati +39
Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time…
Spirals and clumps in V960 Mon: signs of planet formation via gravitational instability around an FU Ori star?
P. Weber, S. Pérez, A. Zurlo +11
The formation of giant planets has traditionally been divided into two pathways: core accretion and gravitational instability. However, in recent years, gravitational instability h…
