The Ophiuchus DIsc Survey Employing ALMA (ODISEA)-III: the evolution of substructures in massive discs at 3-5 au resolution
Lucas A. Cieza, Camilo González-Ruilova, Antonio S. Hales +15
We present 1.3 mm continuum ALMA long-baseline observations at 3-5 au resolution of 10 of the brightest discs from the Ophiuchus DIsc Survey Employing ALMA (ODISEA) project. We ide…
A Tale of Two Transition Disks: ALMA long-baseline observations of ISO-Oph 2 reveal two closely packed non-axisymmetric rings and a 2 au cavity
Camilo González-Ruilova, Lucas A. Cieza, Antonio S. Hales +12
ISO-Oph 2 is a wide-separation (240 au) binary system where the primary star harbors a massive (M 40 M) ring-like disk with a dust cavity 50 au in r…
The X-ray properties of Eta Carinae during its 2020 X-ray minimum
Amit Kashi, David A. Principe, Noam Soker +1
The massive binary system Eta Carinae is characterized by intense colliding winds that form shocks and emit X-rays. The system is highly eccentric (), resulting in modu…
ALMA Observations of Young Eruptive Stars: continuum disk sizes and molecular outflows
Antonio S. Hales, Sebastián Pérez, Camilo Gonzalez-Ruilova +7
We present Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm observations of four young, eruptive star-disk systems at 0.4" resolution: two FUors (V582 Aur and V900 Mon),…
Evidence for magnetic activity at starbirth: a powerful X-ray flare from the Class 0 protostar HOPS 383
Nicolas Grosso, Kenji Hamaguchi, David Principe +1
Context. Class 0 protostars represent the earliest evolutionary stage of solar-type stars, during which the majority of the system mass resides in an infalling envelope of gas and…
The Ophiuchus DIsc Survey Employing ALMA (ODISEA). II. The effect of stellar multiplicity on disc properties
Alice Zurlo, Lucas A. Cieza, Sebastián Pérez +9
We present Adaptive Optics (AO) near infrared (NIR) observations using VLT/NACO and Keck/NIRC2 of ODISEA targets. ODISEA is an ALMA survey of the entire population of circumstellar…
Spatially resolved velocity structure in jets of DF Tau and UY Aur A
Anastasiia V Uvarova, Hans Moritz Günther, David A. Principe +1
Young stars accrete mass and angular momentum from their circumstellar disks. Some of them also drive outflows, which can be distinguished in optical forbidden emission lines (FELs…
The Chandra High Resolution X-ray Spectrum of Quiescent Emission from Sgr A*
L. Corrales, F. K. Baganoff, Q. D. Wang +7
In quiescence, Sgr A* is surprisingly dim, shining 100,000 times less than expected for its environment. This problem has motivated a host of theoretical models to explain radiativ…
