Resolving period aliases for TESS monotransits recovered during the extended mission
Benjamin F. Cooke, Don Pollacco, David R. Anderson +8
We set out to explore how best to mitigate the number of period aliases for a transiting TESS system with two identified transits separated by a large time period on the order of y…
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…
An eclipsing M-dwarf close to the hydrogen burning limit from NGTS
Jack S. Acton, Michael R. Goad, Sarah L. Casewell +20
We present the discovery of NGTS J0930-18, an extreme mass ratio eclipsing M-dwarf binary system with an early M-dwarf primary and a late M-dwarf secondary close to the hydrogen bu…
The EBLM project. VII. Spin-orbit alignment for the circumbinary planet host EBLM J0608-59 A/TOI-1338 A
Vedad Kunovac Hodžić, Amaury H. M. J. Triaud, David V. Martin +14
A dozen short-period detached binaries are known to host transiting circumbinary planets. In all circumbinary systems so far, the planetary and binary orbits are aligned within a c…
NGTS clusters survey -- II. White-light flares from the youngest stars in Orion
James A. G. Jackman, Peter J. Wheatley, Jack S. Acton +18
We present the detection of high energy white-light flares from pre-main sequence stars associated with the Orion complex, observed as part of the Next Generation Transit Survey (N…
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…
TOI-1338: TESS' First Transiting Circumbinary Planet
Veselin B. Kostov, Jerome A. Orosz, Adina D. Feinstein +65
We report the detection of the first circumbinary planet found by TESS. The target, a known eclipsing binary, was observed in sectors 1 through 12 at 30-minute cadence and in secto…
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…
NGTS J214358.5-380102 -- NGTS discovery of the most eccentric known eclipsing M-Dwarf binary system
Jack S. Acton, Michael R. Goad, Liam Raynard +23
We present the discovery of NGTS J214358.5-380102, an eccentric M-dwarf binary discovered by the Next Generation Transit Survey. The system period of 7.618 days is greater than man…
A remnant planetary core in the hot-Neptune desert
David J. Armstrong, Théo A. Lopez, Vardan Adibekyan +91
The interiors of giant planets remain poorly understood. Even for the planets in the Solar System, difficulties in observation lead to large uncertainties in the properties of plan…
A long period (P = 61.8-d) M5V dwarf eclipsing a Sun-like star from TESS and NGTS
Samuel Gill, Benjamin F. Cooke, Daniel Bayliss +27
The Transiting Exoplanet Survey Satellite (TESS) has produced a large number of single transit event candidates which are being monitored by the Next Generation Transit Survey (NGT…
