Cloud Atlas: High-contrast Time-resolved Observations of Planetary-mass Companions
- Yifan Zhou, D. Apai, +11 authors A. Burgasser
- Physics
- 31 January 2019
Directly imaged planetary-mass companions offer unique opportunities in atmospheric studies of exoplanets. They share characteristics of both brown dwarfs and transiting exoplanets, and therefore are… Expand
Variability in a Young, L/T Transition Planetary-Mass Object
- B. Biller, Johanna Vos, +15 authors T. Henning
- Physics
- 26 October 2015
As part of our ongoing NTT SoFI survey for variability in young free-floating planets and low mass brown dwarfs, we detect significant variability in the young, free-floating planetary mass object… Expand
Cloud Atlas: Rotational Spectral Modulations and potential Sulfide Clouds in the Planetary-mass, Late T-type Companion Ross 458C.
- E. Manjavacas, D. Apai, +11 authors J. Radigan
- Physics
- 26 March 2019
Measurements of photometric variability at different wavelengths provide insights into the vertical cloud structure of brown dwarfs and planetary-mass objects. In seven Hubble Space Telescope… Expand

Confirming the least massive members of the Pleiades star cluster
- M. Osorio, V. S. Béjar, N. Lodieu, E. Manjavacas
- Physics
- 5 December 2017
We present optical photometry (i- and Z-band) and low-resolution spectroscopy (640-1015 nm) of very faint candidate members (J = 20.2-21.2 mag) of the Pleiades star cluster (120 Myr). The main goal… Expand
Deep $z$-band observations of the coolest Y dwarf
- T. Kopytova, I. Crossfield, +7 authors D. Kopon
- Physics
- 21 October 2014
WISE J085510.83-071442.5 (hereafter, WISE 0855-07) is the coolest Y dwarf known to date and is located at a distance of 2.31$\pm 0.08$ pc, giving it the fourth largest parallax of any known star or… Expand
Cloud Atlas: Hubble Space Telescope Near-Infrared Spectral Library of Brown Dwarfs, Planetary-mass companions, and hot Jupiters
- E. Manjavacas, D. Apai, +12 authors P. Kauffmann
- Physics
- 10 December 2018
Bayesian atmospheric retrieval tools can place constraints on the properties of brown dwarfs and hot Jupiters atmospheres. To fully exploit these methods, high signal-to-noise spectral libraries with… Expand
Testing the existence of optical linear polarization in young brown dwarfs
- E. Manjavacas, P. Miles-P'aez, +5 authors M. Fang
- Physics
- 21 March 2017
Linear polarization can be used as a probe of the existence of atmospheric condensates in ultracool dwarfs. Models predict that the observed linear polarization increases withthe degree of… Expand
