Velocity Curve Analysis of the Spectroscopic Binary Stars PV Pup, HD 141929, EE Cet and V921 Her by Nonlinear Regression
Stars binaries eclipsing—stars binaries spectroscopic
2009/5/12
We use the method introduced by Karami & Mohebi (2007),
and Karami & Teimoorinia (2007) which enable us to derive the orbital
parameters of the spectroscopic binary stars by the nonlinear least squa...
Analysis of Plasma and Field Conditions during Some Intensely Geoeffective Transient Solar/Interplanetary Disturbances of Solar Cycle 23
Earth:geomagnetic storm Sun:solar and wind magnetosphere coupling
2009/5/7
The problem of solar wind-magnetosphere coupling is investigated for intense geomagnetic storms (Dst γ -100 nT) that occurred during solar cycle 23. For this purpose interplanetary plasma and fie...
Analysis of Enhanced Velocity Signals Observed during Solar Flares
Sun:oscillations Sun:sunspots Sun:flares
2009/5/7
Solar flares are known to release a large amount of energy. It
is believed that the flares can excite velocity oscillations in active regions.
We report here the changes in velocity signals in three...
Analysis of Ion Charge States in Solar Wind and CMEs
Solar wind and CMEs Fe ion charge states dielectronic recombination
2009/5/6
We discuss needs in dielectronic recombination data motivated
by recent work directed at a quantitative understanding of ion charge
states of various elements observed in situ in the solar wind and ...
Helioseismic Ring Analysis of CME Source Regions
Sun coronal mass ejections oscillations magnetic field
2009/5/6
We apply the ring diagram technique to source regions of
halo coronal mass ejections (CMEs) to study changes in acoustic mode
parameters before, during, and after the onset of CMEs.We find that CME

2010/10/29
We present the analysis of V and R light curves of the late type contact binary V523 Cas for the season of 2006. These observations make part of the monitoring program aimed at studying the long-term ...
THE ANALYSIS OF TOTAL SOLAR ECLIPSE OBSERVATIONS ON AUGUST 11th, 1999 IN KIKINDA
TOTAL SOLAR ECLIPSE KIKINDA
2009/3/16
Because of poor meteorological conditions, the obtained observational
material has not an even distribution in time. Therefore a special method
was devised for treating this material. Using this met...
A VARIANCE-COMPONENT ANALYSIS FOR THE LONGITUDE NETWORK ADJUSMENT
VARIANCE-COMPONENT ANALYSIS LONGITUDE NETWORK
2009/3/13
The problem of weights in the task of longitude-network adjustment
has not been solved yet because the structure of the observational variances
is unknown. During the adjustment of a part of the Eur...
TIME SERIES ANALYSIS OF LONG TERM FULL DISK OBSERVATIONS OF THE Mn I 539.4 nm SOLAR LINE
Sun activity-Methods statistical
2009/3/2
The equivalent width and central depth data of Mn 539.4 nm solar
spectral line, observed in the period from 1979 to 1992 at Kitt Peak Observatory, was
analyzed in pursuit for periodic changes. As th...
PROGRESS REPORT ON THE MONITORING ACTIVE LATE-TYPE STARS IN 2005/2006 AND THE ANALYSIS OF V523 CAS
Stars late type-Stars activity-starspots-Stars individual V523 Cas
2009/2/18
We present the light curve analysis of late-type binary V523 Cas
for the season 2005. The spot has been revealed on the secondary. According to
theoretical considerations, the spot appeared to be ho...

2009/2/16
An analysis of the relation between radio surface brightness and
diameter, so-called §¡D relation, for planetary nebulae (PNe) is presented: i) the
theoretical § ¡ D relation for the evo...
