Stellar & Planetary Parameters for K2's Late Type Dwarf Systems from C1 to C5
Arturo O. Martinez, Ian J. M. Crossfield, Joshua E. Schlieder +12
The NASA K2 mission uses photometry to find planets transiting stars of various types. M dwarfs are of high interest since they host more short period planets than any other type o…
Four Sub-Saturns with Dissimilar Densities: Windows into Planetary Cores and Envelopes
Erik A. Petigura, Evan Sinukoff, Eric Lopez +12
We present results from a Keck/HIRES radial velocity campaign to study four sub-Saturn-sized planets, K2-27b, K2-32b, K2-39b, and K2-108b, with the goal of understanding their mass…
Deep -band observations of the coolest Y dwarf
Taisiya G. Kopytova, Ian J. M. Crossfield, Niall R. Deacon +7
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 pc, giving it the fourth largest parallax of…
Orbital Monitoring of the AstraLux Large M-dwarf Multiplicity Sample
Markus Janson, Carolina Bergfors, Wolfgang Brandner +6
Orbital monitoring of M-type binaries is essential for constraining their fundamental properties. This is particularly useful in young systems, where the extended pre-main sequence…
The VLT/NaCo large program to probe the occurrence of exoplanets and brown dwarfs at wide orbits: II- Survey description, results and performances
G. Chauvin, A. Vigan, M. Bonnefoy +29
In anticipation of the VLT/SPHERE planet imager guaranteed time programs, we have conducted a preparatory survey of 86 stars between 2009 and 2013 in order to identify new faint co…
The VLT/NaCo Large program to probe the occurrence of exoplanets and brown dwarfs in wide orbits: I- Sample definition and characterization
S. Desidera, E. Covino, S. Messina +28
Young, nearby stars are ideal targets to search for planets using the direct imaging technique. The determination of stellar parameters is crucial for the interpretation of imaging…
