X-ray line coincidence photopumping in a solar flare
F. P. Keenan, K. Poppenhaeger, M. Mathioudakis +6
Line coincidence photopumping is a process where the electrons of an atomic or molecular species are radiatively excited through the absorption of line emission from another specie…
Unconscious Gender Bias in Academia: from PhD Students to Professors
K. Poppenhaeger
In an academic landscape where female physicists are still strongly underrepresented, underlying causes like unconscious gender bias deserve specific attention. Members of academia…
NGTS-1b: A hot Jupiter transiting an M-dwarf
Daniel Bayliss, Edward Gillen, Philipp Eigmuller +40
We present the discovery of NGTS-1b, a hot-Jupiter transiting an early M-dwarf host () in a P=2.674d orbit discovered as part of the Next Generation Tra…
Three small transiting planets around the M dwarf host star LP 358-499
R. Wells, K. Poppenhaeger, C. A. Watson
We report on the detection of three transiting small planets around the low-mass star LP 358-499 (K2-133), using photometric data from the Kepler-K2 mission. Using multiband photom…
Tidal effects on stellar activity
K. Poppenhaeger
The architecture of many exoplanetary systems is different from the solar system, with exoplanets being in close orbits around their host stars and having orbital periods of only a…
Centroid vetting of transiting planet candidates from the Next Generation Transit Survey
Maximilian N. Günther, Didier Queloz, Edward Gillen +25
The Next Generation Transit Survey (NGTS), operating in Paranal since 2016, is a wide-field survey to detect Neptunes and super-Earths transiting bright stars, which are suitable f…
An Improved Age-Activity Relationship for Cool Stars older than a Gigayear
R. S. Booth, K. Poppenhaeger, C. A. Watson +2
Stars with convective envelopes display magnetic activity, which decreases over time due to the magnetic braking of the star. This age-dependence of magnetic activity is well-studi…
