A critical analysis of three methods of estimating distances to cataclysmic variables (CVs) is performed. These methods, by Ak et al., Beuermann, and Knigge, all use near-infrared (JHK or Ks) magnitud...
Extrapolations of solar photospheric vector magnetograms into three-dimensional magnetic fields in the chromosphere and corona are usually done under the assumption that the fields are force-free. The...
We present a new set of high resolution dust extinction maps of the nearby and essentially starless Pipe Nebula molecular cloud. The maps were constructed from a concerted deep nearinfrared imaging s...
We present two independent methods for studying the global stellar parameter space (mass M, age, chemical composition X0, Z0) of HD 49933 with seismic data. Using a local minimization and an MCMC algo...
Using data from the Heliospheric Imagers (HIs) onboard STEREO, it is possible to derive the direction of propagation of coronal mass ejections (CMEs) in addition to their speed with a variety of metho...
We measure the spin of XTE J1550-564 in two ways: by modelling the thermal continuum spectrum of the accretion disc, and independently by modeling the broad red wing of the reflection fluorescence Fe-...
Our purpose is to find which is the most reliable one among various oxygen abundance determination methods.We will test the validity of several different oxygen abundance determination methods using m...
In arXiv:0911.2150, Rutger van Haasteren seeks to criticize the nested sampling algorithm for Bayesian data analysis in general and its MultiNest implementation in particular. He introduces a new meth...
Measurement of Double Stars with a CCD Camera:Two Methods
We analyse different observational data related to the problem of intrinsic magnetic field strength in small-scale fluxtubes outside sunspots. We conclude that the kG range of fluxtube fields follow...
An essential progress in astrophysics and CB evolution theory started about 1970 thanks to the development of computer models enabling synthesizing of the light curves and those of line-of-sight vel...
COMPARISON OF THE SMOOTHING METHODS:PRELIMINARY RESULTS
Three different methods, Whittaker - Robinson - Vondrak (WRV), cubic spline (SPL) and Expansion of the Elementary Trigonometric and Exponential Functions (ETE), are applied to differences in star po...
