Science with an ngVLA: Exploring Protostellar Disk Formation with the ngVLA
John Tobin, Patrick Sheehan, Doug Johnstone +1
The formation and evolution of disks early in the protostellar phase is an area of study in which the ngVLA is poised to make significant breakthroughs. The high-sensitivity and re…
Science with an ngVLA: New Frontiers in Protostellar Multiplicity with the ngVLA
John Tobin, Patrick Sheehan, Doug Johnstone
The ngVLA will enable significant advances in our understanding of the formation and evolution of multiple star systems in the protostellar phase, building upon the breakthroughs e…
Methanol and its relation to the water snowline in the disk around the young outbursting star V883 Ori
Merel L. R. van 't Hoff, John J. Tobin, Leon Trapman +5
We report the detection of methanol in the disk around the young outbursting star V883 Ori with the Atacama Large Millimeter/submillimeter Array (ALMA). Four transitions are observ…
Protoplanetary Disk Properties in the Orion Nebula Cluster: Initial Results from Deep, High-Resolution ALMA Observations
J. A. Eisner, H. G. Arce, N. P. Ballering +13
We present ALMA 850 m continuum observations of the Orion Nebula Cluster that provide the highest angular resolution ( AU) and deepest sensitivity…
Multiple Gaps in the Disk of the Class I Protostar GY 91
Patrick Sheehan, Josh Eisner
We present the highest spatial resolution ALMA observations to date of the Class I protostar GY 91 in the Ophiuchus L1688 molecular cloud complex. Our 870 m and 3 mm dust co…
The Orbit of the Companion to HD 100453A: Binary-Driven Spiral Arms in a Protoplanetary Disk
Kevin Wagner, Ruobing Dong, Patrick Sheehan +9
HD 100453AB is a 10+/-2 Myr old binary whose protoplanetary disk was recently revealed to host a global two-armed spiral structure. Given the relatively small projected separation…
