Ultralight bosonic dark matter in white dwarfs and potential observational consequences
Nicolas Sanchis-Gual, Paula Izquierdo
Fluid and ultralight bosonic dark matter can interact through gravity to form stable fermion-boson stars, which are static and regular mixed solutions of the Einstein-Euler-(comple…
Velocity-imaging the rapidly precessing planetary disc around the white dwarf HE 1349-2305 using Doppler tomography
Christopher J. Manser, Erik Dennihy, Boris T. Gänsicke +11
The presence of planetary material in white dwarf atmospheres, thought to be accreted from a dusty debris disc produced via the tidal disruption of a planetesimal, is common. Appro…
A transmission spectrum of the planet candidate WD 1856+534 b and a lower limit to its mass
R. Alonso, P. Rodríguez-Gil, P. Izquierdo +7
The cool white dwarf WD 1856+534 was found to be transited by a Jupiter-sized object with a mass at or below 14 M. We used the GTC telescope to obtain and analyse phot…
GD424 -- a helium-atmosphere white dwarf with a large amount of trace hydrogen in the process of digesting a rocky planetesimal
Paula Izquierdo, Odette Toloza, Boris T. Gänsicke +5
The photospheric metal pollution of white dwarfs is now well-established as the signature of the accretion of planetary debris. However, the origin of the trace hydrogen detected i…
HORuS transmission spectroscopy of 55 Cnc e
H. M. Tabernero, C. Allende Prieto, M. R. Zapatero Osorio +16
The High Optical Resolution Spectrograph (HORuS) is a new high-resolution echelle spectrograph available on the 10.4 m Gran Telescopio Canarias (GTC). We report on the first HORuS…
white dwarfs within 40 pc II: the volume-limited northern hemisphere sample
Jack McCleery, Pier-Emmanuel Tremblay, Nicola Pietro Gentile Fusillo +6
We present an overview of the sample of northern hemisphere white dwarfs within 40 pc of the Sun detected from Data Release 2 (DR2). We find that 521 sources are spectroscop…
