Discovery of the first outbursting hot subdwarf binary: ZTF J0007+4804
E. Stringer, T. Kupfer, K. Deshmukh +10
Hot subdwarf binaries with white dwarf companions with orbital periods of less than two hours are progenitor candidates for massive single white dwarfs as well as a variety of ther…
The Transit Timing and Transmission Spectrum of Hot Jupiter WASP-43 b from a decade of Multi-band Transit Follow-up Observations
Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +21
We present a new set of 35 transit light curves of the hot Jupiter WASP-43~b, obtained through the SPEARNET network. These datasets were analyzed together with previously published…
Investigation of Transit Timing and an Optical Transmission Spectrum of the Hot Jupiter WASP-11 b
Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +15
WASP-11~b/HAT-P-10~b is an inflated hot Jupiter, which has a low density that makes it a good target for atmospheric studies using the transmission spectroscopy technique. In this…
GOTO identification and broadband modelling of the counterpart to the SVOM GRB 250818B
S. Belkin, G. P. Lamb, K. Ackley +61
Rapid localisation and follow-up of gamma-ray bursts (GRBs) increasingly rely on low-latency triggers from new missions coupled to wide-field robotic optical facilities. We present…
Gaia20fnr: A binary-lens microlensing event with full orbital motion revealed by four space telescopes
M. Wicker, Å. Wyrzykowski, M. Hundertmark +49
The microlensing event Gaia20fnr is a long-duration, non-caustic-crossing binary-lens event at high Galactic latitude. Triggered by a photometric rise detected by the Gaia space mi…
Constraining Lens Masses in Moderately to Highly Magnified Microlensing Events from Gaia
U. Pylypenko, Å. Wyrzykowski, P. J. MikoÅajczyk +57
Microlensing events provide a unique way to detect and measure the masses of isolated, non-luminous objects, particularly dark stellar remnants. Under certain conditions, it is pos…
