TESS Hunt for Young and Maturing Exoplanets (THYME) IX: a 27 Myr extended population of Lower-Centaurus Crux with a transiting two-planet system

Mackenna L. Wood, Andrew W. Mann, Madyson G. Barber +35

We report the discovery and characterization of a nearby (~ 85 pc), older (27 +/- 3 Myr), distributed stellar population near Lower-Centaurus-Crux (LCC), initially identified by se…

Periodic stellar variability from almost a million NGTS light curves

Joshua T. Briegal, Edward Gillen, Didier Queloz +25

We analyse 829,481 stars from the Next Generation Transit Survey (NGTS) to extract variability periods. We utilise a generalisation of the autocorrelation function (the G-ACF), whi…

TESS Data for Asteroseismology (T'DA) Stellar Variability Classification Pipeline: Set-Up and Application to the Kepler Q9 Data

Jeroen Audenaert, James S. Kuszlewicz, Rasmus Handberg +16

The NASA Transiting Exoplanet Survey Satellite (TESS) is observing tens of millions of stars with time spans ranging from 27 days to about 1 year of continuous observations.…

Ground-based detection of G star superflares with NGTS

James A. G. Jackman, Peter J. Wheatley, Chloe E. Pugh +19

We present high cadence detections of two superflares from a bright G8 star (V = 11.56) with the Next Generation Transit Survey (NGTS). We improve upon previous superflare detectio…

Statistical Properties of Quasi-Periodic Pulsations in White-Light Flares Observed With Kepler

C. E. Pugh, D. J. Armstrong, V. M. Nakariakov +1

We embark on a study of quasi-periodic pulsations (QPPs) in the decay phase of white-light stellar flares observed by Kepler. Out of the 1439 flares on 216 different stars detected…

K2 Variable Catalogue II: Machine Learning Classification of Variable Stars and Eclipsing Binaries in K2 Fields 0-4

D. J. Armstrong, J. Kirk, K. W. F. Lam +9

We are entering an era of unprecedented quantities of data from current and planned survey telescopes. To maximise the potential of such surveys, automated data analysis techniques…

Insights into internal effects of common-envelope evolution using the extended Kepler mission

J. J. Hermes, B. T. Gaensicke, A. Bischoff-Kim +14

We present an analysis of the binary and physical parameters of a unique pulsating white dwarf with a main-sequence companion, SDSS J1136+0409, observed for more than 77 d during t…

K2 Variable Catalogue: Variable Stars and Eclipsing Binaries in K2 Campaigns 1 and 0

D. J. Armstrong, J. Kirk, K. W. F. Lam +6

We have created a catalogue of variable stars found from a search of the publicly available K2 mission data from Campaigns 1 and 0. This catalogue provides the identifiers of 8395…

KIC 2856960: the impossible triple star

T. R. Marsh, D. J. Armstrong, P. J. Carter

KIC 2856960 is a star in the Kepler field which was observed by Kepler for 4 years. It shows the primary and secondary eclipses of a close binary of 0.258d as well as complex dippi…

A Catalogue of Temperatures for Kepler Eclipsing Binary Stars

D. J. Armstrong, Y. Gómez Maqueo Chew, F. Faedi +1

We have combined the Kepler Eclipsing Binary Catalogue with information from the HES, KIS and 2MASS photometric surveys to produce spectral energy distribution fits to over 2600 ec…
