Study of sdO models: mode trapping
C. Rodríguez-López, A. Moya, R. Garrido +3
We present the first description of mode trapping for sdO models. Mode trapping of gravity modes caused by the He/H chemical transition is found for a particular model, providing a…
Study of sdO models. Pulsation Analysis
C. Rodríguez-López, A. Moya, R. Garrido +3
We have explored the possibility of driving pulsation modes in models of sdO stars in which the effects of element diffusion, gravitational settling and radiative levitation have b…
The rapidly pulsating sdO star, SDSS J160043.6+074802.9
C. Rodríguez-López, A. E. Lynas-Gray, D. Kilkenny +7
A spectroscopic analysis of SDSS J160043.6+074802.9, a binary system containing a pulsating subdwarf-O (sdO) star with a late-type companion, yields Teff = 70 000 +/- 5000 K and lo…
Big Bang Nucleosynthesis: The Strong Nuclear Force meets the Weak Anthropic Principle
J. MacDonald, D. J. Mullan
Contrary to a common argument that a small increase in the strength of the strong force would lead to destruction of all hydrogen in the big bang due to binding of the diproton and…
