Mass loss and orbital period decrease in detached chromospherically active binaries
O. Demircan, Z. Eker, Y. Karatas +1
The secular evolution of the orbital angular momentum (OAM), the systemic mass and the orbital period of 114 chromospherically active binaries (CABs) were investi…
The investigation of ELAIS field by Vega photometry: Absolute - magnitude dependent on the Galactic model parameters
S. Bilir, S. Karaali, G. Gilmore
We estimate the density laws of the Galactic stellar populations as a function of absolute magnitude in a near-polar Galactic field. The density laws are determined by the direct f…
Early-Time Observations of the GRB 050319 Optical Transient
R. M. Quimby, E. S. Rykoff, S. A. Yost +18
We present the unfiltered ROTSE-III light curve of the optical transient associated with GRB 050319 beginning 4 s after the cessation of gamma-ray activity. We fit a power-law func…
Optical Lightcurve & Cooling Break of GRB 050502A
S. A. Yost, K. Alatalo, E. S. Rykoff +29
We present lightcurves of the afterglow of GRB050502A, including very early data at t-t_{GRB} < 60s. The lightcurve is composed of unfiltered ROTSE-IIIb optical observations from 4…
The orbital period of Nova V2540 Ophiuchi (2002)
T. Ak, A. Retter, A. Liu
We present the results of 26 nights of CCD photometry of the nova V2540 Oph (2002) from 2003 and 2004. We find a period of 0.284781 +/- 0.000006 d (6.8347 +/- 0.0001 h) in the data…
Parametrization of the Galactic Structure by two exponentials
S. Karaali
We parametrized the total structure of the Galaxy in cylindrical coordinates by radial and vertical exponentials up to z=10 kpc, covering thin disc, thick disc, and the inner spher…
