The Magellan-TESS Survey I: Survey Description and Mid-Survey Results
Johanna Teske, Sharon Xuesong Wang, Angie Wolfgang +66
revealed that roughly one-third of Sun-like stars host planets orbiting within 100 days and between the size of Earth and Neptune. How do these planets form, what are they…
On the Brittle-to-Ductile Transition of the As-cast TiVNbTa Refractory High-entropy Alloy
Robert James Scales, David Edward John Armstrong, Angus J Wilkinson +1
The fracture properties of as-cast TiVNbTa, a refractory high-entropy alloy (RHEA), were investigated using four-point bending tests from -139C to 20C under a strain-rate of 10-3 s…
An Ultra-Hot Neptune in the Neptune desert
James S. Jenkins, Matías R. Díaz, Nicolás T. Kurtovic +81
About one out of 200 Sun-like stars has a planet with an orbital period shorter than one day: an ultra-short-period planet (Sanchis-ojeda et al. 2014; Winn et al. 2018). All of the…
NGTS-12b: A sub-Saturn mass transiting exoplanet in a 7.53 day orbit
Edward M. Bryant, Daniel Bayliss, Louise D. Nielsen +35
We report the discovery of the transiting exoplanet NGTS-12b by the Next Generation Transit Survey (NGTS). The host star, NGTS-12, is a V=12.38 mag star with an effective temperatu…
Exoplanet Validation with Machine Learning: 50 new validated Kepler planets
David J. Armstrong, Jevgenij Gamper, Theodoros Damoulas
Over 30% of the ~4000 known exoplanets to date have been discovered using 'validation', where the statistical likelihood of a transit arising from a false positive (FP), non-planet…
NGTS-11 b / TOI-1847 b: A transiting warm Saturn recovered from a TESS single-transit event
Samuel Gill, Peter J. Wheatley, Benjamin F. Cooke +37
We report the discovery of NGTS-11 b (=TOI-1847 b), a transiting Saturn in a 35.46-day orbit around a mid K-type star (Teff=5050 K). We initially identified the system from a singl…
YOUNG Star detrending for Transiting Exoplanet Recovery (YOUNGSTER) -- I. A search for young exoplanets in Sectors 1-5 of the TESS Full-Frame-Images
Matthew P. Battley, Don Pollacco, David J. Armstrong
Young (<1Gyr) exoplanets represent a critically important area of exoplanet research, as they offer the opportunity to learn about the formation and early dynamic history of exopla…
Masses for the seven planets in K2-32 and K2-233. Four diverse planets in resonant chain and the first young rocky worlds
J. Lillo-Box, T. A. Lopez, A. Santerne +18
High-precision planetary densities are key to derive robust atmospheric properties for extrasolar planets. Measuring precise masses is the most challenging part, especially in mult…
Simultaneous TESS and NGTS Transit Observations of WASP-166b
Edward M. Bryant, Daniel Bayliss, James McCormac +21
We observed a transit of WASP-166 b using nine NGTS telescopes simultaneously with TESS observations of the same transit. We achieved a photometric precision of 152 ppm per 30 minu…
Mass determinations of the three mini-Neptunes transiting TOI-125
L. D. Nielsen, D. Gandolfi, D. J. Armstrong +77
The Transiting Exoplanet Survey Satellite, TESS, is currently carrying out an all-sky search for small planets transiting bright stars. In the first year of the TESS survey, steady…
