UV-driven Chemistry as a Signpost for Late-stage Planet Formation
Jenny K. Calahan, Edwin A. Bergin, Arthur D. Bosman +14
The chemical reservoir within protoplanetary disks has a direct impact on planetary compositions and the potential for life. A long-lived carbon-and nitrogen-rich chemistry at cold…
Sulphur monoxide emission tracing an embedded planet in the HD 100546 protoplanetary disk
Alice S. Booth, John D. Ilee, Catherine Walsh +4
Molecular line observations are powerful tracers of the physical and chemical conditions across the different evolutionary stages of star, disk and planet formation. Using the high…
Molecules with ALMA at Planet-forming Scales (MAPS). A Circumplanetary Disk Candidate in Molecular Line Emission in the AS 209 Disk
Jaehan Bae, Richard Teague, Sean M. Andrews +29
We report the discovery of a circumplanetary disk (CPD) candidate embedded in the circumstellar disk of the T Tauri star AS 209 at a radial distance of about 200 au (on-sky separat…
CO Line Emission Surfaces and Vertical Structure in Mid-Inclination Protoplanetary Disks
Charles J. Law, Sage Crystian, Richard Teague +18
High spatial resolution CO observations of mid-inclination (30-75°) protoplanetary disks offer an opportunity to study the vertical distribution of CO emission and temperature. The…
Unveiling the outer dust disc of TW Hya with deep ALMA observations
John D. Ilee, Catherine Walsh, Jeff Jennings +5
The radial extent of millimetre dust in protoplanetary discs is often far smaller than that of their gas, mostly due to processes such as dust growth and radial drift. However, it…
Discovery of a 500 au Protobinary in the Massive Prestellar Core G11.92-0.61 MM2
C. J. Cyganowski, J. D. Ilee, C. L. Brogan +4
We present high-resolution (< ~160 au) Atacama Large Millimeter/submillimeter Array (ALMA) 1.3 mm observations of the high-mass prestellar core candidate G11.92-0.61 MM2, which rev…
