The Architecture of the GW Ori Young Triple Star System and Its Disk: Dynamical Masses, Mutual Inclinations, and Recurrent Eclipses

Ian Czekala, Sean M. Andrews, Guillermo Torres +15

We present spatially and spectrally resolved Atacama Large Millimeter/submillimeter Array (ALMA) observations of gas and dust orbiting the pre-main sequence hierarchical triple sta…

Hydrogen-Poor Superluminous Supernovae from the Pan-STARRS1 Medium Deep Survey

R. Lunnan, R. Chornock, E. Berger +31

We present light curves and classification spectra of 17 hydrogen-poor superluminous supernovae (SLSNe) from the Pan-STARRS1 Medium Deep Survey (PS1 MDS). Our sample contains all o…

ALMA Observations of the Young Substellar Binary System 2M1207

L. Ricci, P. Cazzoletti, I. Czekala +10

We present ALMA observations of the 2M1207 system, a young binary made of a brown dwarf with a planetary-mass companion at a projected separation of about 40 au. We detect emission…

Improving and Assessing Planet Sensitivity of the GPI Exoplanet Survey with a Forward Model Matched Filter

Jean-Baptiste Ruffio, Bruce Macintosh, Jason J. Wang +49

We present a new matched filter algorithm for direct detection of point sources in the immediate vicinity of bright stars. The stellar Point Spread Function (PSF) is first subtract…

Disentangling Time Series Spectra with Gaussian Processes: Applications to Radial Velocity Analysis

Ian Czekala, Kaisey S. Mandel, Sean M. Andrews +4

Measurements of radial velocity variations from the spectroscopic monitoring of stars and their companions are essential for a broad swath of astrophysics, providing access to the…

Placing the spotted T Tauri star LkCa 4 on an HR diagram

Michael A. Gully-Santiago, Gregory J. Herczeg, Ian Czekala +12

Ages and masses of young stars are often estimated by comparing their luminosities and effective temperatures to pre-main sequence stellar evolution tracks, but magnetic fields and…
