No Period Change in Two Long-Period AM CVn Binaries
Matthew J. Green, Thomas R. Marsh, Jan van Roestel +25
Ultracompact binary systems, consisting of two compact objects in an orbit , should exhibit measurable rates of orbital period change () due t…
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…
Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM
A. Fraser Gillan, Åukasz Wyrzykowski, PrzemysÅaw J. MikoÅajczyk +69
Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…
Unveiling the white dwarf in the eclipsing polar HU Aquarii
A. D. Schwope, T. R. Marsh, S. G. Parsons +2
We present an analysis of high-speed u- and r-band photometry of the eclipsing polar HU Aquarii that was obtained with ULTRACAM mounted on the VLT. The observations were performed…
