Particles under radiation thrust in Schwarzschild space-time from a flux perpendicular to the equatorial plane
Donato Bini, Andrea Geralico, Robert T. Jantzen +1
Motivated by the picture of a thin accretion disc around a black hole, radiating mainly in the direction perpendicular to its plane, we study the motion of test particles interacti…
(Sr,Na)(Zn,Mn)2As2: A new diluted ferromagnetic semiconductor with the hexagonal CaAl2Si2 type structure
B. J. Chen, K. Zhao, Z. Deng +15
A new diluted ferromagnetic semiconductor (Sr,Na)(Zn,Mn)2As2 is reported, in which charge and spin doping are decoupled via Sr/Na and Zn/Mn substitutions, respectively, being disti…
Validation of the Frequency Modulation technique applied to the pulsating delta Sct - gamma Dor eclipsing binary star KIC 8569819
Donald W. Kurtz, Kelly M. Hambleton, Hiromoto Shibahashi +2
KIC 8569819 is an eclipsing binary star with an early F primary and G secondary in a 20.85-d eccentric orbit. The primary is a delta Sct - gamma Dor star pulsating in both p modes…
(Ca,Na)(Zn,Mn)2As2: a new spin & charge doping decoupled diluted ferromagnetic semiconductor with hexagonal CaAl2Si2 structure
K. Zhao, B. J. Chen, Z. Deng +17
Here we report the successful synthesis of a spin- & charge-decoupled diluted magnetic semiconductor (Ca,Na)(Zn,Mn)2As2, crystallizing into the hexagonal CaAl2Si2 structure. The co…
The Secret Lives of Cepheids: Evolutionary Changes and Pulsation-Induced Shock Heating in the Prototype Classical Cepheid δ Cep
Scott G. Engle, Edward F. Guinan, Graham M. Harper +2
Over the past decade, the Secret Lives of Cepheids (SLiC) program has been carried out at Villanova University to study aspects and behaviors of classical Cepheids that are still n…
Scattering of particles by radiation fields: a comparative analysis
Donato Bini, Andrea Geralico, Maria Haney +1
The features of the scattering of massive neutral particles propagating in the field of a gravitational plane wave are compared with those characterizing their interaction with an…
