Are Inner Disc Misalignments Common? ALMA Reveals an Isotropic Outer Disc Inclination Distribution for Young Dipper Stars
M. Ansdell, E. Gaidos, C. Hedges +12
Dippers are a common class of young variable star exhibiting day-long dimmings with depths of up to several tens of percent. A standard explanation is that dippers host nearly edge…
Bright C2H emission in protoplanetary disks in Lupus: high volatile C/O>1 ratios
A. Miotello, S. Facchini, E. F. van Dishoeck +6
ALMA surveys have shown that CO emission in protoplanetary disks is much fainter than expected. Accordingly, CO-based gas masses and gas/dust ratios are orders of magnitude lower t…
An Exo-Kuiper Belt and An Extended Halo around HD 191089 in Scattered Light
Bin Ren, Élodie Choquet, Marshall D. Perrin +70
We have obtained Hubble Space Telescope STIS and NICMOS, and Gemini/GPI scattered light images of the HD 191089 debris disk. We identify two spatial components: a ring resembling K…
Planetesimals Around Stars with TESS (PAST): I. Transient Dimming of a Binary Solar Analog at the End of the Planet Accretion Era
E. Gaidos, T. Jacobs, D. LaCourse +16
We report detection of quasi-periodic (1.5 day) dimming of HD 240779, the solar-mass primary in a 5" visual binary (also TIC 284730577), by the Transiting Exoplanet Survey Satellit…
Effects of Ringed Structures and Dust Size Growth on Millimeter Observations of Protoplanetary Disks
Ya-Ping Li, Hui Li, Luca Ricci +7
The growth of solids from sub-micron to millimeter and centimeter sizes is the early step toward the formation of planets inside protoplanetary disks (PPDs). However, such processe…
The Ophiuchus DIsk Survey Employing ALMA (ODISEA): Disk Dust Mass Distributions across Protostellar Evolutionary Classes
Jonathan P. Williams, Lucas Cieza, Antonio Hales +5
As protostars evolve from optically faint / infrared bright (Class I) sources to optically bright / infrared faint (Class II) the solid material in their surrounding disks accumula…
