Constraining Co-Varying Coupling Constants from Globular Cluster Age

چکیده
Equations governing the evolution of a star involve multiple coupling constants. Thus, time it spends as main-sequence can be expected to depend on whether or not such constants vary over scale stellar evolution. When belongs globular cluster, star’s age cannot exceed that and latter Universe. This fact used constrain verify variation constants, i.e., speed light c, gravitational constant G, Planck h, Boltzmann k. We have estimated analytically from takes synthesize all its hydrogen into helium under fixed varying scenarios. we permitted interrelated four (G~c3~h3~k3/2) differentiated between cosmological energy local conservation laws, could show established in our earlier studies, G˙/G=3c˙/c=3h˙/h=1.5k˙/k=3.90±0.04×10−10 yr−1 at current cosmic is consistent with present work. Nevertheless, challenge remains come up an experiment, astrometric terrestrial, unequivocally prove falsify predicted variation.

Constraining white - dwarf kicks in globular clusters : III . Cluster Heating
Recent observations of white dwarfs in globular clusters indicate that these stars may get a velocity kick during their time as giants. This velocity kick could originate naturally if the mass loss while on the asymptotic giant branch is slightly asymmetric. The kicks may be large enough to dramatically change the radial distribution of young white dwarfs, giving them larger energies than other...
متن کاملAge Constraints for an M31 Globular Cluster from Seds-fit
We have constrained the age of the globular cluster S312 in the Andromeda galaxy (M31) by comparing its multicolor photometry with theoretical stellar population synthesis models. This is both a check on the age of this globular cluster, as well a check on our methodology. Main-sequence photometry has been the most direct method for determining the age of a star cluster. S312 was observed as pa...
متن کاملAge Estimation of Extragalactic Globular Cluster Systems
After taking into account, for the first time, the detailed systematic variation of horizontal-branch (HB) morphology with age and metallicity, our population synthesis models show that the integrated Hβ index is significantly affected by the presence of blue HB stars. Our models indicate that the strength of the Hβ index increases as much as 0.75 Å due to blue HB stars. According to our models...
متن کاملConstraining axion–nucleon coupling constants from measurements of effective Casimir pressure by means of micromachined oscillator
Stronger constraints on the pseudoscalar coupling constants of an axion to a proton and a neutron are obtained from an indirect measurement of the effective Casimir pressure between two Au-coated plates by means of micromechanical torsional oscillator. For this purpose, the additional effective pressure due to two-axion exchange is calculated. The role of boundary effects and the validity regio...
متن کاملVarying constants.
We review properties of theories for the variation of gravitation and fine structure 'constants'. We highlight some general features of the cosmological models that exist in these theories with reference to recent quasar data that are consistent with time variation in the fine structure constant since a redshift of 3.5. The behaviour of a simple class of varying-alpha cosmologies is outlined in...
