A Near-infrared Variability Survey of Young Planetary-mass Objects
Pengyu Liu, Beth A. Biller, Johanna M. Vos +12
We present a photometric variability survey of young planetary-mass objects using the New Technology Telescope in the Js and Ks bands. Surface gravity plays an important role in th…
Simultaneous, Multi-Wavelength Variability Characterization of the Free-Floating Planetary Mass Object PSO J318.5-22
Beth Biller, Johanna Vos, Esther Buenzli +15
We present simultaneous HST WFC3 + Spitzer IRAC variability monitoring for the highly-variable young (20 Myr) planetary-mass object PSO J318.5-22. Our simultaneous HST + Spit…
The Gemini NICI Planet-Finding Campaign: The Frequency of Planets around Young Moving Group Stars
Beth A. Biller, Michael C. Liu, Zahed Wahhaj +18
We report results of a direct imaging survey for giant planets around 80 members of the Beta Pic, TW Hya, Tucana-Horologium, AB Dor, and Hercules-Lyra moving groups, observed as pa…
The Gemini NICI Planet-Finding Campaign: The Frequency of Giant Planets around Young B and A Stars
Eric L. Nielsen, Michael C. Liu, Zahed Wahhaj +22
We have carried out high contrast imaging of 70 young, nearby B and A stars to search for brown dwarf and planetary companions as part of the Gemini NICI Planet-Finding Campaign. O…
