Constraining the neutrino magnetic dipole moment from white dwarf pulsations
(Iop Publishing, 2014-08)
Pulsating white dwarf stars can be used as astrophysical laboratories to constrain the properties of weakly interacting particles. Comparing the cooling rates of these stars with the expected values from theoretical models ...
On the periodic variations of secondary cosmic rays and the geomagnetic Pc4 pulsations in BMAr
(Springer VerlagNew York, 1997)
The dynamical mass of a classical Cepheid variable star in an eclipsing binary systems
(2010)
Stellar pulsation theory provides a means of determining the masses of pulsating classical Cepheid supergiants—it is the pulsation that causes their luminosity to vary. Such pulsational masses are found to be smaller than ...
The Optical Gravitational Lensing Experiment. The OGLE-III Catalog of Variable Stars. VI. Delta Scuti Stars in the Large Magellanic Cloud
(2010)
The sixth part of the OGLE-III catalog of Variable Stars presents \delta Sct pulsators in the Large Magellanic Cloud. Altogether 2786 variable stars were found and amongst them 92 are multi-mode objects, including 67 stars ...
High-amplitude σ-Scutis in the Large Magellanic Cloud
(2010)
We present 2323 High-Amplitude \delta-Scuti (HADS) candidates discovered in the Large Magellanic Cloud (LMC) by the SuperMACHO survey (Rest et al. 2005). Frequency analyses of these candidates reveal that several are ...
First axion bounds from a pulsating helium-rich white dwarf star
(IOP Publishing, 2016-08)
The Peccei-Quinn mechanism proposed to solve the CP problem of Quantum Chromodynamics has as consequence the existence of axions, hypothetical weakly interacting particles whose mass is constrained to be on the sub-eV ...
