A Cavity of Large Grains in the Disk Around the Group II Herbig Ae/Be Star HD 142666
Adam E. Rubinstein, Enrique Macias, Catherine C. Espaillat +3
Herbig Ae/Be (HAeBe) stars have been classified into Group I or Group II, which were initially thought to be flared and flat disks, respectively. Several Group I sources have been…
First radial velocity results from the MINiature Exoplanet Radial Velocity Array (MINERVA)
Maurice L. Wilson, Jason D. Eastman, Matthew A. Cornachione +52
The MINiature Exoplanet Radial Velocity Array (MINERVA) is a dedicated observatory of four 0.7m robotic telescopes fiber-fed to a KiwiSpec spectrograph. The MINERVA mission is to d…
Multi-epoch Ultraviolet HST Observations of Accreting Low-mass Stars
Connor Robinson, Catherine Espaillat
Variability is a defining characteristic of young low-mass stars that are still accreting material from their primordial protoplanetary disk. Here we present the largest \textit{HS…
Multiple rings in the transitional disk of GM Aurigae revealed by VLA and ALMA
Enrique Macias, Catherine C. Espaillat, Alvaro Ribas +6
Our understanding of protoplanetary disks is rapidly departing from the classical view of a smooth, axisymmetric disk. This is in part thanks to the high angular resolution that (s…
Empirical Determination of the Lithium 6707.856 Ã Wavelength in Young Stars
Justyn Campbell-White, Carlo F. Manara, Aurora Sicilia-Aguilar +20
Absorption features in stellar atmospheres are often used to calibrate photocentric velocities for kinematic analysis of further spectral lines. The Li feature at 6708 Ã is…
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…
