Fitting dwarf galaxy rotation curves with conformal gravity
Fitting dwarf galaxy rotation curves conformal gravity
2011/10/20
We continue our study of the application of the conformal gravity theory to galactic rotation curves. Previously we had studied a varied 111 spiral galaxy sample consisting of high surface brightness ...
Effects of dust on light-curves of εAur type stars
Accretion, accretion disks – Scattering – binaries: eclipsing – circumstellar matter – Stars: individual: ǫ Aur
2011/10/11
\epsilon Auriga is one of the most mysterious objects on the sky. Prior modeling of its light-curve assumed a dark, inclined, non-transparent or semi-transparent, dusty disk with a central hole. The h...
Galactic Phase Transition at E_c= 0.11 eV from Rotation Curves of Cored LSB and nonperturbative Dark Matter Mass
Galactic Phase Transition Rotation Curves Cored LSB nonperturbative Dark Matter
2011/10/8
We analyze the a set of seventeen rotation curves of Low Surface Brightness (LSB) galaxies from the The HI Nearby Galaxy Survey (THINGS) with different mass models to study the core structure and to d...
Confronting 2D delayed-detonation models with light curves and spectra of Type Ia supernovae
supernovae: general
2011/9/26
We compare models for Type Ia supernova (SN Ia) light curves and spectra with an extensive set of observations. The models come from a recent survey of 44 two-dimensional delayed-detonation models com...

Fitting galactic rotation curves with conformal gravity and a global quadratic potential
galactic rotation conformal gravity global quadratic potential
2010/11/16
We apply the conformal gravity theory to a sample of 110 spiral galaxies whose rotation curve
data points extend well beyond the optical disk. With no free parameters other than galactic mass to ligh...
Old White Dwarf Stars with Some Hydrogen -- Cooling Curves
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
We present theoretical analysis on old white dwarf stars with \emph{some} hydrogen, that possess a mass of surface hydrogen from $1\times10^{-11}M_{\sun}$ to $1\times10^{-7}M_{\sun}$. The evolution of...
The shapes of light curves of Mira-type variables
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/31
Using a sample of 454 mira light curves from the ASAS survey we study the shape of the light variations in this kind of variable stars.

On the Analysis of Light Curves in Asteroseismology
Fourier analysis noise sources ill-posed problems
2009/5/12
We provide a detailed introduction to the main problems arising
when analyzing light curves in asteroseismology. Attention is first paid to
the signal model delivered by the pulsating stars and to t...
