BEAST begins: Sample characteristics and survey performance of the B-star Exoplanet Abundance Study
Markus Janson, Vito Squicciarini, Philippe Delorme +20
While the occurrence rate of wide giant planets appears to increase with stellar mass at least up through the A-type regime, B-type stars have not been systematically studied in la…
Spitzer Variability Properties of Low-Gravity L Dwarfs
Johanna M. Vos, Beth A. Biller, Katelyn N. Allers +17
We present \textit{Spitzer Space Telescope} variability monitoring observations of three low-gravity L dwarfs with previous detections of variability in the near-IR, 2MASS J0045+16…
Strong H emission and signs of accretion in a circumbinary planetary mass companion from MUSE
Simon C. Eriksson, Rubén Asensio Torres, Markus Janson +4
Context. Intrinsic H emission can be advantageously used to detect substellar companions because it improves contrasts in direct imaging. Characterising this emission from accre…
Detection of new strongly variable brown dwarfs in the L/T transition
Simon C. Eriksson, Markus Janson, Per Calissendorff
*Abbreviated abstract* Context: Brown dwarfs in the spectral range L9-T3.5, within the so called L/T transition, have been shown to be variable at higher amplitudes and with greate…
The B-Star Exoplanet Abundance Study: a co-moving 16-25 Mjup companion to the young binary system HIP 79098
Markus Janson, Ruben Asensio-Torres, Damien Andre +13
Wide low-mass substellar companions are known to be very rare among low-mass stars, but appear to become increasingly common with increasing stellar mass. However, B-type stars, wh…
A Search for Variability in Exoplanet Analogues and Low-Gravity Brown Dwarfs
Johanna M. Vos, Beth A. Biller, Mariangela Bonavita +18
We report the results of a -band survey for photometric variability in a sample of young, low-gravity objects using the New Technology Telescope (NTT) and the United Kingdom Inf…
