Multitaper magnitude-squared coherence for time series with missing data: Understanding oscillatory processes traced by multiple observables
Sarah E. Dodson-Robinson, Charlotte Haley
To explore the hypothesis of a common source of variability in two time series, observers may estimate the magnitude-squared coherence (MSC), which is a frequency-domain view of th…
Astro2020 Science White Paper: Dynamical Processes in the Planet-Forming Environment
Peregrine McGehee, Alan Boss, Laird Close +3
The transfer of circumstellar disk mass and momentum onto the protostar and out into the environment occurs via a variety of mechanisms including magnetospheric accretion, jets, ou…
The Close Companion Mass-Ratio Distribution of Intermediate-Mass Stars
Kevin Gullikson, Adam Kraus, Sarah Dodson-Robinson
Binary stars and higher-order multiple systems are an ubiquitous outcome of star formation, especially as the system mass increases. The companion mass-ratio distribution is a uniq…
Direct Spectral Detection: An Efficient Method to Detect and Characterize Binary Systems
Kevin Gullikson, Adam Kraus, Sarah Dodson-Robinson +6
Young, intermediate-mass stars are experiencing renewed interest as targets for direct-imaging planet searches. However, these types of stars are part of multiple systems more ofte…
Hot Stars With Cool Companions
Kevin Gullikson, Adam Kraus, Sarah Dodson-Robinson
Young intermediate-mass stars have become high-priority targets for direct-imaging planet searches following the recent discoveries of planets orbiting e.g. HR 8799 and Beta Pictor…
WISE Y Dwarfs As Probes of the Brown Dwarf-Exoplanet Connection
C. Beichman, Christopher R. Gelino, J. Davy Kirkpatrick +5
We have determined astrometric positions for 15 WISE-discovered late-type brown dwarfs (6 T8-9 and 9 Y dwarfs) using the Keck II telescope, the Spitzer Space Telescope, and the Hub…
