Chemical Variation in Molecular Cloud Cores in the Orion A Cloud
Chemical Variation Molecular Cloud Cores the Orion A Cloud
2011/1/10
We have observed molecular cloud cores in the Orion A giant molecular cloud (GMC) in CCS, HC3N, DNC, and HN13C to study their chemical characteristics. We have detected CCS in the Orion A GMC for the ...
Space-time variation of the electron-to-proton mass ratio in a Weyl model
Space-time variation the electron-to-proton mass ratio
2011/1/13
We consider a phenomenological model where the effective fermion masses depend on the local value of Weyl tensor as a possible explanation for the recent data indicating a space-time variation of the...
