Identification of Likely Methane Absorption Features in the Optical Spectra of Titan

Sirinrat Sithajan, Lalita Kaewbiang, Hugh R. A. Jones +2

The optical spectra of Titan reveal a rich set of absorption features, most of which are likely associated with methane (CH). Methane is a key molecule in planetary and exoplan…

Applied Machine-Learning Models to Identify Spectral Sub-Types of M Dwarfs from Photometric Surveys

Sirinrat Sithajan, Sukanya Meethong

M dwarfs are the most abundant stars in the Solar Neighborhood and they are prime targets for searching for rocky planets in habitable zones. Consequently, a detailed characterizat…

HiFLEx -- a highly flexible package to reduce cross-dispersed echelle spectra

Ronny Errmann, Neil Cook, Guillem Anglada-Escudé +8

We describe a flexible data reduction package for high resolution cross-dispersed echelle data. This open-source package is developed in Python and includes optional GUIs for most…

The first super-Earth Detection from the High Cadence and High Radial Velocity Precision Dharma Planet Survey

Bo Ma, Jian Ge, Matthew Muterspaugh +23

The Dharma Planet Survey (DPS) aims to monitor about 150 nearby very bright FGKM dwarfs (within 50 pc) during 20162020 for low-mass planet detection and characterization using t…

Exploring the Brown Dwarf Desert: New Substellar Companions from the SDSS-III MARVELS Survey

Nolan Grieves, Jian Ge, Neil Thomas +27

Planet searches using the radial velocity technique show a paucity of companions to solar-type stars within ~5 AU in the mass range of ~10 - 80 M. This deficit, know…

Very Low-Mass Stellar and Substellar Companions to Solar-like Stars From MARVELS VI: A Giant Planet and a Brown Dwarf Candidate in a Close Binary System HD 87646

Bo Ma, Jian Ge, Alex Wolszczan +34

We report the detections of a giant planet (MARVELS-7b) and a brown dwarf candidate (MARVELS-7c) around the primary star in the close binary system, HD 87646. It is the first close…
