Far-infrared to millimeter data of protoplanetary disks: dust growth in the Taurus, Ophiuchus, and Chamaeleon I star-forming regions
Álvaro Ribas, Catherine C. Espaillat, Enrique Macías +7
Far-infrared and (sub)millimeter fluxes can be used to study dust in protoplanetary disks, the building blocks of planets. Here, we combine observations from the Herschel Space Obs…
An Incipient Debris Disk in the Chamaeleon I Cloud
C. C. Espaillat, Á. Ribas, M. K. McClure +5
The point at which a protoplanetary disk becomes a debris disk is difficult to identify. To better understand this, here we study the 40~AU separation binary T~54 in the Cham…
Periodic Eclipses of the Young Star PDS 110 Discovered with WASP and KELT Photometry
H. P. Osborn, J. E. Rodriguez, M. A. Kenworthy +28
We report the discovery of eclipses by circumstellar disc material associated with the young star PDS 110 in the Ori OB1a association using the SuperWASP and KELT surveys. PDS 110…
Time Dependent Models of Magnetospheric Accretion onto Young Stars
Connor Robinson, James Owen, Catherine Espaillat +1
Accretion onto Classical T Tauri stars is thought to take place through the action of magnetospheric processes, with gas in the inner disk being channeled onto the star's surface b…
Polarized disk emission from Herbig Ae/Be stars observed using Gemini Planet Imager: HD 144432, HD 150193, HD 163296, and HD 169142
John D. Monnier, T. J. Harries, A. Aarnio +11
In order to look for signs of on-going planet formation in young disks, we carried out the first J-band polarized emission imaging of the Herbig Ae/Be stars HD 150193, HD 163296, a…
