Calibration of the Halpha Age-Activity relation for M dwarfs
Rocio Kiman, Jacqueline K. Faherty, Kelle L. Cruz +6
In this work, we calibrate the relationship between Halpha emission and M dwarf ages. We compile a sample of 892 M dwarfs with Halpha equivalent width (HaEW) measurements from the…
Exploring the age dependent properties of M and L dwarfs using Gaia and SDSS
Rocio Kiman, Sarah J. Schmidt, Ruth Angus +3
We present a sample of 74,216 M and L dwarfs constructed from two existing catalogs of cool dwarfs spectroscopically identified in the Sloan Digital Sky Survey (SDSS). We cross-mat…
The Na 8200 Angstrom Doublet as an Age Indicator in Low-Mass Stars
Joshua E. Schlieder, Sebastien Lepine, Emily Rice +3
We investigate the use of the gravity sensitive neutral sodium (NaI) doublet at 8183 Angstroms 8195 Angstroms (Na 8200 Angstrom doublet) as an age indicator for M dwarfs. We measur…
High Resolution Infrared Imaging & Spectroscopy of the Z Canis Majoris System During Quiescence & Outburst
Sasha Hinkley, Lynne Hillenbrand, Ben R. Oppenheimer +21
We present adaptive optics photometry and spectra in the JHKL-bands along with high spectral resolution K-band spectroscopy for each component of the Z Canis Majoris system. Our hi…
Discovery of Two Nearby, Peculiar L Dwarfs from the 2MASS Proper Motion Survey: Young or Metal-Rich?
Dagny L. Looper, J. Davy Kirkpatrick, Roc M. Cutri +9
We present the discovery of two nearby L dwarfs from our 2MASS proper motion search, which uses multi-epoch 2MASS observations covering ~4700 square degrees of sky. 2MASS J18212815…
IDEAS: Immersive Dome Experiences for Accelerating Science
Jacqueline K. Faherty, Mark SubbaRao, Ryan Wyatt +29
Astrophysics lies at the crossroads of big datasets (such as the Large Synoptic Survey Telescope and Gaia), open source software to visualize and interpret high dimensional dataset…
Electric Field Conjugation with the Project 1640 coronagraph
Eric Cady, Christoph Baranec, Charles Beichman +25
The Project 1640 instrument on the 200-inch Hale telescope at Palomar Observatory is a coronagraphic instrument with an integral field spectrograph at the back end, designed to fin…
