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…
Searching for outbursts from Symbiotic Binaries in GOTO and ATLAS data
G. Ramsay, K. Ackley, S. Belkin +46
Symbiotic Binaries contain a white dwarf accreting material from a red giant star through a wind. We present the results of a search for outbursts from Symbiotic Binaries using pho…
The ZZ Ceti Instability Strip for The Most Massive White Dwarf Pulsators
Gracyn Jewett, Mukremin Kilic, Adam Moss +10
We present time-series photometry of 31 massive DA white dwarfs with within the ZZ Ceti instability strip from the Montreal White Dwarf Database 100 pc sampl…
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…
Testing disc reprocessing models for AGN optical variability by comparison of X-ray and optical power spectra of NGC 4395
Max Beard, Ian McHardy, Keith Horne +11
It is generally thought that AGN optical variability is produced, at least in part, by reprocessing of central X-rays by a surrounding accretion disc, resulting in wavelength-depen…
