Detection of a giant flare displaying quasi-periodic pulsations from a pre-main sequence M star with NGTS
James A. G. Jackman, Peter J. Wheatley, Chloe E. Pugh +18
We present the detection of an energetic flare on the pre-main sequence M3 star NGTS J121939.5-355557, which we estimate as only 2 Myr old. The flare had an energy of $3.2\pm^{0.4}…
K2-265 b: A Transiting Rocky Super-Earth
K. W. F. Lam, A. Santerne, S. G. Sousa +34
We report the discovery of the super-Earth K2-265 b detected with K2 photometry. The planet orbits a bright (V_mag = 11.1) star of spectral type G8V with a period of 2.37 days. We…
NGTS-4b: A sub-Neptune Transiting in the Desert
Richard G. West, Edward Gillen, Daniel Bayliss +48
We report the discovery of NGTS-4b, a sub-Neptune-sized planet transiting a 13th magnitude K-dwarf in a 1.34d orbit. NGTS-4b has a mass M=M_E and radius R=…
A low-mass eclipsing binary within the fully convective zone from the NGTS
S. L. Casewell, L. Raynard, C. A. Watson +22
We have discovered a new, near-equal mass, eclipsing M dwarf binary from the Next Generation Transit Survey. This system is only one of 3 field age ( 1 Gyr), late M dwarf eclips…
Global Climate and Atmospheric Composition of the Ultra-Hot Jupiter WASP-103b from HST and Spitzer Phase Curve Observations
Laura Kreidberg, Michael R. Line, Vivien Parmentier +12
We present thermal phase curve measurements for the hot Jupiter WASP-103b observed with Hubble/WFC3 and Spitzer/IRAC. The phase curves have large amplitudes and negligible hotspot…
An Earth-sized exoplanet with a Mercury-like composition
A. Santerne, B. Brugger, D. J. Armstrong +43
The Earth, Venus, Mars, and some extrasolar terrestrial planets have a mass and radius that is consistent with a mass fraction of about 30% metallic core and 70% silicate mantle. A…
Automatic vetting of planet candidates from ground based surveys: Machine learning with NGTS
David J. Armstrong, Maximilian N. Günther, James McCormac +22
State of the art exoplanet transit surveys are producing ever increasing quantities of data. To make the best use of this resource, in detecting interesting planetary systems or in…
Unmasking the hidden NGTS-3Ab: a hot Jupiter in an unresolved binary system
Maximilian N. Günther, Didier Queloz, Edward Gillen +36
We present the discovery of NGTS-3Ab, a hot Jupiter found transiting the primary star of an unresolved binary system. We develop a joint analysis of multi-colour photometry, centro…
NGTS-2b: An inflated hot-Jupiter transiting a bright F-dwarf
Liam Raynard, Michael R. Goad, Edward Gillen +42
We report the discovery of NGTS-2b, an inflated hot-Jupiter transiting a bright F5V star (2MASS J14202949-3112074; = K), discovered as part of the Ne…
The XUV environments of exoplanets from Jupiter-size to super-Earth
George W. King, Peter J. Wheatley, Michael Salz +8
Planets that reside close-in to their host star are subject to intense high-energy irradiation. Extreme-ultraviolet (EUV) and X-ray radiation (together, XUV) is thought to drive ma…
The Transiting Exoplanet Community Early Release Science Program for JWST
Jacob L. Bean, Kevin B. Stevenson, Natalie M. Batalha +99
The James Webb Space Telescope (JWST) presents the opportunity to transform our understanding of planets and the origins of life by revealing the atmospheric compositions, structur…
An ultra-short period rocky super-Earth with a secondary eclipse and a Neptune-like companion around K2-141
Luca Malavolta, Andrew W. Mayo, Tom Louden +44
Ultra-short period (USP) planets are a class of low mass planets with periods shorter than one day. Their origin is still unknown, with photo-evaporation of mini-Neptunes and in-si…
