Are the Luminosities of RR Lyrae Stars Affected by Second Parameter Effects? [PDF]

open access: yes, 1995
There is a serious discrepancy between the distance to the LMC derived from the Cepheid Period-Luminosity relation and that obtained by using the Galactic calibration for the luminosity of RR Lyrae stars. It is suggested that this problem might be due to

Discovery of the Host Cluster for the Fundamental Cepheid Calibrator Zeta Gem

open access: yes, 2012
New and existing CORAVEL, UBVJHKs, HST, HIP/Tycho, ARO, KPNO, and DAO observations imply that the fundamental Cepheid calibrator Zeta Gem is a cluster member. The following parameters were inferred for Zeta Gem from cluster membership and are tied to new

Quantum fluctuation of ferroelectric order in polar metals

open access: yesnpj Quantum Materials, 2023
The polar metallic phase is an unusual metallic phase of matter containing long-range ferroelectric (FE) order in the electronic and atomic structure. Distinct from the typical FE insulating phase, this phase spontaneously breaks the inversion symmetry ...

A large muon EDM from dark matter

open access: yesJournal of High Energy Physics, 2023
We explore a model of dark matter (DM) that can explain the reported discrepancy in the muon anomalous magnetic moment and predict a large electric dipole moment (EDM) of the muon.
