Could the Magnetic Star HD 135348 Possess a Rigidly Rotating Magnetosphere?
Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth +4
We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star e…
Three new pulsating sdB stars discovered with SuperWASP
Daniel L. Holdsworth, Roy H. Østensen, Barry Smalley +1
We present an analysis of three new pulsating subdwarf B stars discovered in the SuperWASP archive. Two of the stars, J1938+5609 and J0902-0720, are p-mode pulsators; J1938+5609 sh…
Temporal resolution of a pre-maximum halt in a Classical Nova: V5589 Sgr observed with STEREO HI-1B
S. P. S. Eyres, D. Bewsher, Y. Hillman +5
Classical novae show a rapid rise in optical brightness over a few hours. Until recently the rise phase, particularly the phenomenon of a pre-maximum halt, was observed sporadicall…
Pulsation versus metallicism in Am stars as revealed by LAMOST and WASP
B. Smalley, V. Antoci, D. L. Holdsworth +13
We present the results of a study of a large sample of A and Am stars with spectral types from LAMOST and light curves from WASP. We find that, unlike normal A stars, Sct pulsa…
HD 24355 observed by the Kepler K2 mission: A rapidly oscillating Ap star pulsating in a distorted quadrupole mode
Daniel L. Holdsworth, Donald W. Kurtz, Barry Smalley +4
We present an analysis of the first Kepler K2 mission observations of a rapidly oscillating Ap (roAp) star, HD 24355 (). The star was discovered in SuperWASP broadband phot…
KIC 7582608: A new Kepler roAp star with frequency variability
Daniel L. Holdsworth, Barry Smalley, Donald W. Kurtz +3
We analyse the fifth roAp star reported in the Kepler field, KIC 7582608, discovered with the SuperWASP project. The object shows a high frequency pulsation at 181.7324 d (P…
