SPECULOOS -- Ultracool Dwarf Transit Survey: Target List and Strategy
D. Sebastian, M. Gillon, E. Ducrot +20
One of the most promising avenues for the detailed study of temperate Earth-sized exoplanets is the detection of such planets in transit in front of stars small and nearby enough t…
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…
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…
Complex Modulation of Rapidly Rotating Young M Dwarfs: Adding Pieces to the Puzzle
Maximilian N. Günther, David A. Berardo, Elsa Ducrot +37
New sets of young M dwarfs with complex, sharp-peaked, and strictly periodic photometric modulations have recently been discovered with Kepler/K2 (scallop shells) and TESS (complex…
TRAPPIST-1: Global Results of the Spitzer Exploration Science Program {\it Red Worlds}
Elsa Ducrot, M. Gillon, L. Delrez +18
With more than 1000 hours of observation from Feb 2016 to Oct 2019, the Spitzer Exploration Program Red Worlds (ID: 13067, 13175 and 14223) exclusively targeted TRAPPIST-1, a nearb…
GJ 273: On the formation, dynamical evolution and habitability of a planetary system hosted by an M dwarf at 3.75 parsec
Francisco J. Pozuelos, Juan C. Suárez, Gonzalo C. de Elía +11
Planets orbiting low-mass stars such as M dwarfs are now considered a cornerstone in the search for life-harbouring planets. GJ273 is a planetary system orbiting an M dwarf only 3.…
Earth: a 3.14-day Earth-sized Planet from 's Kitchen Served Warm by the SPECULOOS Team
Prajwal Niraula, Julien de Wit, Benjamin V. Rackham +25
We report on the discovery of a transiting Earth-sized (0.95) planet around an M3.5 dwarf star at 57pc, K2-315b. The planet has a period of 3.14 days, i.e. ${\s…
Photometry and Performance of SPECULOOS-South
C. A. Murray, L. Delrez, P. P. Pedersen +16
SPECULOOS-South, an observatory composed of four independent 1m robotic telescopes, located at ESO Paranal, Chile, started scientific operation in January 2019. This Southern Hemis…
Flare Statistics for Young Stars from a Convolutional Neural Network Analysis of Data
Adina D. Feinstein, Benjamin T. Montet, Megan Ansdell +5
All-sky photometric time-series missions have allowed for the monitoring of thousands of young (Myr) to understand the evolution of stellar activity. Here we dev…
Superflares on the late-type giant KIC 2852961 -- Scaling effect behind flaring at different energy levels
Zs. Kővári, K. Oláh, M. N. Günther +7
The most powerful superflares reaching 10erg bolometric energy are from giant stars. The mechanism behind flaring is supposed to be the magnetic reconnection, which is close…
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…
The First Habitable Zone Earth-Sized Planet From TESS II: Confirms TOI-700 d
Joseph E. Rodriguez, Andrew Vanderburg, Sebastian Zieba +43
We present 4.5m observations of the transit of TOI-700 d, a habitable zone Earth-sized planet in a multiplanet system transiting a nearby M-dwarf star (TIC 150428135,…
