TOI-519 b: a short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis
H. Parviainen, E. Palle, M. R. Zapatero-Osorio +43
Context: We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 RJup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d orbit. Brown dwarfs a…
Phase Curves of Hot Neptune LTT 9779b Suggest a High-Metallicity Atmosphere
Ian J. M. Crossfield, Diana Dragomir, Nicolas B. Cowan +20
Phase curve measurements provide a global view of the composition, thermal structure, and dynamics of exoplanet atmospheres. Although most of the dozens of phase curve measurements…
Spitzer Reveals Evidence of Molecular Absorption in the Atmosphere of the Hot Neptune LTT 9979b
Diana Dragomir, Ian J. M. Crossfield, Bjorn Benneke +27
Non-rocky sub-jovian exoplanets in high irradiation environments are rare. LTT 9979b, also known as TESS Object of Interest (TOI) 193.01, is one of the few such planets discovered…
A Featureless Infrared Transmission Spectrum for the Super-Puff Planet Kepler-79d
Yayaati Chachan, Daniel Jontof-Hutter, Heather A. Knutson +12
Extremely low density planets ('super-puffs') are a small but intriguing subset of the transiting planet population. With masses in the super-Earth range ( M) and…
TESS Reveals a Short-period Sub-Neptune Sibling (HD 86226c) to a Known Long-period Giant Planet
Johanna Teske, Matías R. Díaz, Rafael Luque +44
The Transiting Exoplanet Survey Satellite mission was designed to find transiting planets around bright, nearby stars. Here we present the detection and mass measurement of a small…
The TESS Phase Curve of KELT-1b Suggests a High Dayside Albedo
Thomas G. Beatty, Ian Wong, Tara Fetherolf +12
We measured the optical phase curve of the transiting brown dwarf KELT-1b (TOI 1476, Siverd et al. 2012) using data from the TESS spacecraft. We found that KELT-1b shows significan…
Optical to near-infrared transmission spectrum of the warm sub-Saturn HAT-P-12b
Ian Wong, Björn Benneke, Peter Gao +12
We present the transmission spectrum of HAT-P-12b through a joint analysis of data obtained from the Hubble Space Telescope Space Telescope Imaging Spectrograph (STIS) and Wide Fie…
TESS spots a hot Jupiter with an inner transiting Neptune
Chelsea X. Huang, Samuel N. Quinn, Andrew Vanderburg +48
Hot Jupiters are rarely accompanied by other planets within a factor of a few in orbital distance. Previously, only two such systems have been found. Here, we report the discovery…
Systematic Phase Curve Study of Known Transiting Systems from Year 1 of the TESS Mission
Ian Wong, Avi Shporer, Tansu Daylan +14
We present a systematic phase curve analysis of known transiting systems observed by the Transiting Exoplanet Survey Satellite (TESS) during year one of the primary mission. Using…
