A possible solution to the mass-loss problem in M-type AGB stars
mass-loss problem M-type AGB stars
2010/11/12
Mass loss is a fundamental, observationally well-established feature of AGB stars but many aspects of this process still remain to be understood. To date,self-consistent dynamical models of dust-drive...
Resonant Destruction as a Possible Solution to the Cosmological Lithium Problem
Resonant Destruction Possible Solution Cosmological Lithium Problem
2011/1/7
We explore a nuclear physics resolution to the discrepancy between the predicted standard
BBN abundance of 7Li and its observational determination in metal-poor stars. The the-
oretical 7Li abundanc...

A Mismatch in the Ultraviolet Spectra between Low-Redshift and Intermediate-Redshift Type Ia Supernovae as a Possible Solution to the U-Band Anomaly
Cosmology and Extragalactic Astrophysics (astro-ph.CO) Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/4
We present Keck high-quality rest-frame ultraviolet (UV) through optical spectra of 21 Type Ia supernovae (SNe Ia) in the redshift range 0.11 < z < 0.37 and a mean redshift of 0.22 that were discovere...
Aluminium in Groundwater Possible Solution Equilibria
Aluminium Groundwater Solution Equilibria
2009/10/28
Recent investigations in the west coast region of Sweden has revealed the
occurrence of groundwaters with a pH of around 4 and, further, alarmingly
high concentrations of soluble aluminium. The reas...
