TIC 378898110: A Bright, Short-Period AM CVn Binary in TESS
Matthew J. Green, J. J. Hermes, Brad N. Barlow +22
AM CVn-type systems are ultracompact, helium-accreting binary systems which are evolutionarily linked to the progenitors of thermonuclear supernovae and are expected to be strong G…
Paving the way to simultaneous multi-wavelength astronomy
M. J. Middleton, P. Casella, P. Gandhi +49
Whilst astronomy as a science is historically founded on observations at optical wavelengths, studying the Universe in other bands has yielded remarkable discoveries, from pulsars…
Spin-resolved spectroscopy of the intermediate polar DQ Her
S. Bloemen, T. R. Marsh, D. Steeghs +1
We present high-speed spectroscopic observations of the intermediate polar DQ Herculis. Doppler tomography of two He I lines reveals a spiral density structure in the accretion dis…
Spiral shock detection on eclipse maps: Simulations and Observations
E. T. Harlaftis, R. Baptista, L. Morales-Rueda +2
We perform simulations in order to reveal the effect of observational and physical parameters on the reconstruction of a spiral structure in an accretion disk, using eclipse mappin…
Optical spectra of the carbon-oxygen accretion discs in the ultra-compact X-ray binaries 4U 0614+09, 4U 1543-624 and 2S 0918-549
G. Nelemans, P. G. Jonker, T. R. Marsh +1
We present optical spectra in the range 4600 -- 8600 A for three low-mass X-ray binaries which have been suggested to belong to the class of ultra-compact X-ray binaries based on t…
Orbital periods of twenty two subdwarf B stars
L. Morales-Rueda, P. F. L. Maxted, T. R. Marsh +2
Subdwarf B (sdB) stars are thought to be core helium burning stars with low mass hydrogen envelopes. In recent years it has become clear that many sdB stars lose their hydrogen thr…
