First detection of a disk free of volatile elements around a young A-type star: A sign of collisions between rocky planets?
M. E. van den Ancker, N. P. Gentile Fusillo, T. J. Haworth +7
Aims. We present the first detailed analysis of the astrophysical parameters of the poorly studied Sco-Cen member HD 152384 and its circumstellar environment. Methods. We analyze n…
Weather on Other Worlds. V. The Three Most Rapidly Rotating Ultra-Cool Dwarfs
Megan E. Tannock, Stanimir Metchev, Aren Heinze +7
We present the discovery of rapid photometric variability in three ultra-cool dwarfs from long-duration monitoring with the Spitzer Space Telescope. The T7, L3.5, and L8 dwarfs hav…
New Mid-Infrared Imaging Constraints on Companions and Protoplanetary Disks around six Young Stars
D. J. M. Petit dit de la Roche, N. Oberg, M. E. van den Ancker +13
Mid-infrared imaging traces the sub-micron and micron sized dust grains in protoplanetary disks and it offers constraints on the geometrical properties of the disks and potential c…
Maintaining the Ephemeris of 20 CoRoT Planets: Transit Minimum Times and Potential Transit Timing Variations
Hans J. Deeg, Peter Klagyivik, J. D. Armstrong +11
We present 33 transit minimum times of 20 transiting planets discovered by the CoRoT mission, which have been obtained from ground-based observations since the mission's end in 201…
Cloud Atlas: Unraveling the vertical cloud structure with the time-series spectrophotometry of an unusually red brown dwarf
Ben W. P. Lew, Dániel Apai, Mark Marley +8
Rotational modulations of emission spectra in brown dwarf and exoplanet atmospheres show that clouds are often distributed non-uniformly in these ultracool atmospheres. The spatial…
Cloud Atlas: High-precision HST/WFC3/IR Time-Resolved Observations of Directly-Imaged Exoplanet HD106906b
Yifan Zhou, Dániel Apai, Luigi R. Bedin +10
HD106906b is an ~11, ~15Myr old directly-imaged exoplanet orbiting at an extremely large distance from its host star. The wide separation (7.11 arcsec) between HD…
