HD 213258: A new rapidly oscillating, super slowly rotating, strongly magnetic Ap star in a spectroscopic binary
We report on HD 213258, an Ap star that we recently identified as presenting a unique combination of rare, remarkable properties. Our study of this star is based on ESPaDOnS Stokes I and V data obtained at seven epochs spanning a time interval slightly sho ...
EDP SCIENCES S A2023Can dd excitations mediate pairing?
Christophe Berthod, Francesco Barantani
The Cu-3d states in the high-T-c cuprates are often described as a single band of 3d(x2-y2) states, with the other four 3d states having about 2 to 3 eV higher energy due to the lower-than-octahedral crystal field at the copper sites. However, excitations ...
Amsterdam2023Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
Stephan Morgenthaler, Shuangqing Liao
Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over the time coverage planned for the Gaia DR4, w ...
Les Ulis Cedex A2023Large Orbital Moment of Two Coupled Spin-Half Co Ions in a Complex on Gold
Stefano Rusponi, Chao Li, Boris Sorokin
The magnetic propertiesof transition-metal ions aregenerallydescribed by the atomic spins of the ions and their exchange coupling.The orbital moment, usually largely quenched due the ligand field,is then seen as a perturbation. In such a scheme, S = 1/2 io ...
AMER CHEMICAL SOC2023Secular effects of ultralight dark matter on binary pulsars
Sergey Sibiryakov, Diego Blas Temino
Dark matter (DM) can consist of very light bosons behaving as a classical scalar field that experiences coherent oscillations. The presence of this DM field would perturb the dynamics of celestial bodies, either because the (oscillating) DM stress tensor m ...
