Dark Matter distribution in the Milky Way: microlensing and dynamical constraints
Dark Matter distribution Milky Way microlensing dynamical constraints
2011/10/20
We show that current microlensing and dynamical observations of the Galaxy allow to set interesting constraints on the Dark Matter local density and profile slope towards the galactic centre. Assuming...
Stellar Evolution Constraints on the Triple-Alpha Reaction Rate
Stellar Evolution Constraints Triple-Alpha Reaction Rate
2011/10/19
We investigate the quantitative constraint on the triple-alpha reaction rate based on stellar evolution theory, motivated by the recent significant revision of the rate proposed by nuclear physics cal...
Amplitudes of solar-like oscillations: constraints from red giants in open clusters observed by Kepler
Amplitudes solar-like oscillations: constraints clusters observed Kepler

Scaling relations that link asteroseismic quantities to global stellar properties are important for gaining understanding of the intricate physics that underpins stellar pulsation. The common notion t...
New Constraints on the Primordial Magnetic Field
primordial magnetic field numerical analysis
2010/3/19
We present the newest statistical and numerical analysis of the matter and cosmic microwave background power spectrum with effects of the primordial magnetic field (PMF) included. New limits to the PM...
