Time-resolved Optical Polarization Monitoring of the Most Variable Brown Dwarf
Elena Manjavacas, Paulo A. Miles-Paez, Theodora Karalidi +3
Recent atmospheric models for brown dwarfs suggest that the existence of clouds in substellar objects is not needed to reproduce their spectra, nor their rotationally-induced photo…
Cloud Atlas: Rotational Spectral Modulations and potential Sulfide Clouds in the Planetary-mass, Late T-type Companion Ross 458C
Elena Manjavacas, Daniel Apai, Ben W. P. Lew +11
Measurements of photometric variability at different wavelengths provide insights into the vertical cloud structure of brown dwarfs and planetary-mass objects. In seven Hubble Spac…
Cloud Atlas: High-Contrast Time-Resolved Observations of Planetary-Mass Companions
Yifan Zhou, Dániel Apai, Ben W. P. Lew +11
Directly-imaged planetary-mass companions offer unique opportunities in atmospheric studies of exoplanets. They share characteristics of both brown dwarfs and transiting exoplanets…
Time-resolved image polarimetry of Trappist-1 during planetary transits
P. A. Miles-Páez, M. R. Zapatero Osorio, E. Pallé +1
We obtained linear polarization photometry (-band) and low-resolution spectroscopy (-bands) of Trappist-1, which is a planetary system formed by an M8-type low-mass star and…
Cloud Atlas: Hubble Space Telescope Near-Infrared Spectral Library of Brown Dwarfs, Planetary-mass companions, and hot Jupiters
Elena Manjavacas, Daniel Apai, Yifan Zhou +12
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 spec…
Cloud Atlas: Discovery of Rotational Spectral Modulations in a Low-mass, L-type Brown Dwarf Companion to a Star
Elena Manjavacas, Daniel Apai, Yifan Zhou +11
Observations of rotational modulations of brown dwarfs and giant exoplanets allow the characterization of condensate cloud properties. As of now rotational spectral modulations hav…
Weather on Other Worlds. IV. H emission and photometric variability are not correlated in L0T8 dwarfs
P. A. Miles-Páez, S. A. Metchev, A. Heinze +1
Recent photometric studies have revealed that surface spots that produce flux variations are present on virtually all L and T dwarfs. Their likely magnetic or dusty nature has been…
Testing the existence of optical linear polarization in young brown dwarfs
E. Manjavacas, P. A. Miles-Páez, M. R. Zapatero-Osorio +5
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 d…
Optical and near-infrared linear polarization of low and intermediate-gravity ultra-cool dwarfs
P. A. Miles-Páez, M. R. Zapatero Osorio, E. Pallé +1
We aim to study the optical and near-infrared linear polarimetric properties of a sample of young M7-L7 dwarfs (1-500 Myr) with spectroscopic signatures of low- and interm…
Earth's albedo variations 1998-2014 as measured from ground-based earthshine observations
E Palle, PR Goode, P Pilar Montanes-Rodriguez +11
The Earth's albedo is a fundamental climate parameter for understanding the radiation budget of the atmosphere. It has been traditionally measured from space platforms, but also fr…
The K2-ESPRINT Project. I. Discovery of the Disintegrating Rocky Planet K2-22b with a Cometary Head and Leading Tail
R. Sanchis-Ojeda, S. Rappaport, E. Pallé +28
We present the discovery of a transiting exoplanet candidate in the K2 Field-1 with an orbital period of 9.1457 hr: K2-22b. The highly variable transit depths, ranging from 0…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
