A multi-technique detection of an eccentric giant planet around accelerating star HD 57625
D. Barbato, D. Mesa, V. D'Orazi +42
The synergy between different detection methods is a key asset in exoplanetology, allowing for both precise characterization of detected exoplanets and robust constraints even in t…
A Pilot Study from the First Course-Based Undergraduate Research Experience for Online Degree-Seeking Astronomy Students
Justin Hom, Jennifer Patience, Karen Knierman +2
Research-based active learning approaches are critical for the teaching and learning of undergraduate STEM majors. Course-based undergraduate research experiences (CUREs) are becom…
The MAPS Adaptive Secondary Mirror: First Light, Laboratory Work, and Achievements
Jess A. Johnson, Amali Vaz, Manny Montoya +23
The MMT Adaptive Optics exoPlanet Characterization System (MAPS) is a comprehensive update to the first generation MMT adaptive optics system (MMTAO), designed to produce a facilit…
Constraints on the architecture of the HD 95086 planetary system with the Gemini Planet Imager
Julien Rameau, Eric L. Nielsen, Robert J. De Rosa +31
We present astrometric monitoring of the young exoplanet HD 95086 b obtained with the Gemini Planet Imager between 2013 and 2016. A small but significant position angle change is d…
The Ages of A-Stars I: Interferometric Observations and Age Estimates for Stars in the Ursa Major Moving Group
Jeremy Jones, R. J. White, T. Boyajian +12
We have observed and spatially resolved a set of seven A-type stars in the nearby Ursa Major moving group with the Classic, CLIMB, and PAVO beam combiners on the CHARA Array. At le…
The Brown-dwarf Atmosphere Monitoring (BAM) Project II: Multi-epoch monitoring of extremely cool brown dwarfs
A. Rajan, J. Patience, P. A. Wilson +6
With the discovery of Y dwarfs by the WISE mission, the population of field brown dwarfs now extends to objects with temperatures comparable to those of Solar System planets. To in…
Orbital Motion in Pre-Main Sequence Binaries
G. H. Schaefer, L. Prato, M. Simon +1
We present results from our ongoing program to map the visual orbits of pre-main sequence binaries in the Taurus star forming region using adaptive optics imaging at the Keck Obser…
The Brown dwarf Atmosphere Monitoring (BAM) Project I: The largest near-IR monitoring survey of L- & T-dwarfs
P. A. Wilson, A. Rajan, J. Patience
Using SofI on the 3.5m New Technology Telescope, we have conducted an extensive near-infrared monitoring survey of an unbiased sample of 69 brown dwarfs spanning the L0 and T8 spec…
Testing the universality of star formation - II. Comparing separation distributions of nearby star-forming regions and the field
Robert R. King, Simon P. Goodwin, Richard J. Parker +1
We have measured the multiplicity fractions and separation distributions of seven young star-forming regions using a uniform sample of young binaries. Both the multiplicity fractio…
Spectroscopy across the brown dwarf/planetary mass boundary - I. Near-infrared JHK spectra
J. Patience, R. R. King, R. J. De Rosa +5
With a uniform VLT SINFONI data set of nine targets, we have developed an empirical grid of J,H,K spectra of the atmospheres of objects estimated to have very low substellar masses…
