A hidden population of massive white dwarfs: two spotted K+WD binaries
D. M. Rowan, T. Jayasinghe, M. A. Tucker +10
The identification and characterization of massive () white dwarfs is challenging in part due to their low luminosity. Here we present two candidate single-lin…
A HARPS radial velocity search for planets in the Scorpius-Centaurus association. And its combination with the HARPS and SOPHIE young nearby stars (YNS) surveys
Antoine Grandjean, A. -M. Lagrange, N. Meunier +13
The Scorpius-Centaurus (Sco-Cen) young and nearby massive star-forming region is particularly well suited for extrasolar planet searches with both direct imaging and radial velocit…
Threshold Interface Magnetization Required to Induce Magnetic Proximity Effect
O. Inyang, L. Bouchenoire, B. Nicholson +4
Proximity-induced magnetization (PIM) has broad implications across interface-driven spintronics applications employing spin-currents. We directly determine the scaling between PIM…
Discovery and characterisation of two exoplanets orbiting the metal-poor, solar-type star TOI-5788 with TESS, CHEOPS, and HARPS-N
Ben S. Lakeland, A. Mortier, R. D. Haywood +48
We present the discovery and characterisation of two transiting exoplanets orbiting the metal-poor, solar-type star TOI-5788. From our analysis of six \textit{TESS} sectors and a d…
Discovery of a multi-planetary system orbiting the aged Sun-like star HD 224018
M. Damasso, L. Naponiello, A. Anna John +22
In 2016, Kepler/K2 detected a system of two sub-Neptunes transiting the star HD 224018, one of them showing a mono-transit event. In 2017, we began a spectroscopic follow-up with H…
Thickness-dependence of the Dzyaloshinskii-Moriya interaction in Co2FeAl ultrathin films: effects of the annealing temperature and the heavy metal material
M. Belmeguenai, Y. Roussigné, S. M. Chérif +8
Interfacial Dzyaloshinskii-Moriya interaction (iDMI) has been investigated in Co2FeAl (CFA) ultrathin films of various thicknesses (0.8 nm<tCFA<2 nm) grown on Si substrates, using…
