Einstein Probe discovery of EP J171159.4-333253: an eclipsing neutron star low-mass X-ray binary with clocked bursts
Y. L. Wang, F. Coti Zelati, E. Parent +27
EP J171159.4-333253 is a new neutron-star low-mass X-ray binary discovered in outburst by the Einstein Probe (EP) on 2025 June 23, exhibiting clocked type-I X-ray bursts, eclipses…
A modest change in magnetic braking at the fully convective boundary explains cataclysmic variable evolution
JoaquÃn A. Barraza-Jorquera, Matthias R. Schreiber, Stuart Littlefair +2
Context. For decades, reproducing the orbital period distribution of non-magnetic Cataclysmic Variables (CVs) seemed to require a drastic decrease, usually termed disruption, of an…
Tempawral: A Time-Resolved Retrieval Framework for Variable Brown Dwarfs and Exoplanets
Fei Wang, Ben Burningham, Stuart Littlefair +4
Brown dwarfs and exoplanets are thought to host complex atmospheric phenomena such as clouds, storms, and chemical heterogeneity, akin to weather patterns on Earth. These features…
Unveiling the nature of the Einstein Probe transient EP 241021a
J. Quirola-Vásquez, P. G. Jonker, A. J. Levan +23
We present a multi-wavelength analysis of the fast X-ray transient EP 241021a, discovered by the Wide-field X-ray Telescope aboard the \emph{Einstein Probe} satellite on 2024 Octob…
HiPERCAM and TESS observations of the rapidly rotating M7V star LP 89--187
Gavin Ramsay, J. G. Doyle, Stuart Littlefair +2
The discovery of a significant number of rapidly rotating low mass stars showing no or few flares in TESS observations was a surprise as rapid rotation has previously been taken as…
EP240801a/XRF 240801B: An X-ray Flash Detected by the Einstein Probe and Implications of its Multiband Afterglow
Shuai-Qing Jiang, Dong Xu, Agnes P. C. van Hoof +89
We present multiband observations and analysis of EP240801a, a low-energy, extremely soft gamma-ray burst (GRB) discovered on August 1, 2024 by the Einstein Probe (EP) satellite, w…
