NGTS clusters survey. I. Rotation in the young benchmark open cluster Blanco 1
Edward Gillen, Joshua T. Briegal, Simon T. Hodgkin +18
We determine rotation periods for 127 stars in the ~115 Myr old Blanco 1 open cluster using ~200 days of photometric monitoring with the Next Generation Transit Survey (NGTS). Thes…
NGTS-8b and NGTS-9b: two non-inflated hot-Jupiters
Jean C. Costes, Christopher A. Watson, Claudia Belardi +35
We report the discovery, by the Next Generation Transit Survey (NGTS), of two hot-Jupiters NGTS-8b and NGTS-9b. These orbit a V = 13.68 K0V star (Teff = 5241 +/- 50 K) with a perio…
TOI-222: a single-transit TESS candidate revealed to be a 34-day eclipsing binary with CORALIE, EulerCam and NGTS
Monika Lendl, François Bouchy, Samuel Gill +58
We report the period, eccentricity, and mass determination for the TESS single-transit event candidate TOI-222, which displayed a single 3000 ppm transit in the TESS two-minute cad…
NGTS-10b: The shortest period hot Jupiter yet discovered
James McCormac, Edward Gillen, James A. G. Jackman +44
We report the discovery of a new ultra-short period transiting hot Jupiter from the Next Generation Transit Survey (NGTS). NGTS-10b has a mass and radius of $2.162\,^{+0.092}_{-0.1…
Statistical analysis of Curiosity data shows no evidence for a strong seasonal cycle of Martian methane
Ed Gillen, Paul B Rimmer, David C Catling
Using Gaussian Process regression to analyze the Martian surface methane Tunable Laser Spectrometer (TLS) data reported by Webster (2018), we find that the TLS data, taken as a who…
NGTS-7Ab: An ultra-short period brown dwarf transiting a tidally-locked and active M dwarf
James A. G. Jackman, Peter J. Wheatley, Dan Bayliss +36
We present the discovery of NGTS-7Ab, a high mass brown dwarf transiting an M dwarf with a period of 16.2 hours, discovered as part of the Next Generation Transit Survey (NGTS). Th…
NGTS-5b: a highly inflated planet offering insights into the sub-Jovian desert
Philipp Eigmüller, Alexander Chaushev, Edward Gillen +32
Context: Planetary population analysis gives us insight into formation and evolution processes. For short-period planets, the subJovian desert has been discussed in recent years wi…
NGTS-6b: An Ultra Short Period Hot-Jupiter Orbiting an Old K Dwarf
Jose I. Vines, James S. Jenkins, Jack S. Acton +37
We report the discovery of a new ultra-short period hot Jupiter from the Next Generation Transit Survey. NGTS-6b orbits its star with a period of 21.17~h, and has a mass and radius…
Age Determination in Upper Scorpius with Eclipsing Binaries
Trevor J. David, Lynne A. Hillenbrand, Edward Gillen +4
The Upper Scorpius OB association is the nearest region of recent massive star formation and thus an important benchmark for investigations concerning stellar evolution and planet…
Stellar Flares from the First Tess Data Release: Exploring a New Sample of M-dwarfs
Maximilian N. Günther, Zhuchang Zhan, Sara Seager +21
We perform a study of stellar flares for the 24,809 stars observed with 2 minute cadence during the first two months of the TESS mission. Flares may erode exoplanets' atmospheres a…
