High-resolution Pan-STARRS and SMA observations of IRAS 23077+6707: A giant edge-on protoplanetary disk
Kristina Monsch, Joshua B. Lovell, Ciprian T. Berghea +6
We present resolved images of IRAS 23077+6707 ("Dracula's Chivito") in 1.3 mm/225 GHz thermal dust and CO gas emission with the Submillimeter Array (SMA) and optical (0.5-$0.8\,μ\m…
Dracula's Chivito: discovery of a large edge-on protoplanetary disk with Pan-STARRS
Ciprian T. Berghea, Ammar Bayyari, Michael L. Sitko +6
We report the serendipitous discovery of a large edge-on protoplanetary disk associated with the infrared source IRAS 23077+6707. The disk's apparent size in the Pan-STARRS (PS1) i…
Variability of Disk Emission in Pre-Main Sequence and related Stars. V. Occultation Events from the innermost disk region of the Herbig Ae Star HD 163296
Monika Pikhartova, Zachary C. Long, Korash D. Assani +8
HD 163296 is a Herbig Ae star that underwent a dramatic 0.8 magnitude drop in brightness in the V photometric band in 2001 and a brightening in the near-IR in 2002. Because t…
Variability of Disk Emission in Pre-Main Sequence and Related Stars IV. Investigating the Structural Changes in the Inner Disk Region of MWC 480
Rachel B. Fernandes, Zachary C. Long, Monika Pikhartova +8
We present five epochs of near IR observations of the protoplanetary disk around MWC 480 (HD31648) obtained with the SpeX spectrograph on NASA's Infrared Telescope Facility (IRTF)…
