Astronomical situation in the starry sky in the Neolithic-Chalcolithic in northern latitudes [PDF]
Archaeoastronomy and Ancient Technologies, 2014 The starry sky has been one of the central ancient sources of human knowledge - reflected in myths, religious practice, the arrangements of stone monuments, designs on stone and ceramics, and in the spatial orientation of ancient settlements.

Radiation pattern of the isolated pulsar PSR B1828-11 [PDF]
, 2002 Based on the free precession model of the isolated pulsar PSR B1828-11, Link & Epstein 2001) showed that the observed pulse durations require the radio beam to have a non-standard shape: the beam duration is larger for beam sweeps farthest from the ...

Maria Reiche's line to archaeoastronomy [PDF]
Archaeoastronomy and Ancient Technologies, 2013 Maria Reiche was a German mathematician and archaeologist that, from 1940, devoted her life to the study of the Nazca Lines, the most famous Peruvian geoglyphs, gaining recognition and preservation of them. Created by removing the upper most layer of the

Tkachenko waves, glitches and precession in neutron star
, 2008 Here I discuss possible relations between free precession of neutron stars, Tkachenko waves inside them and glitches. I note that the proposed precession period of the isolated neutron star RX J0720.4-3125 (Haberl et al.

On the precession of accretion discs in X-ray binaries
, 1998 In this letter recent results on the nodal precession of accretion discs in close binaries are applied to the discs in some X-ray binary systems. The ratio between the tidally forced precession period and the binary orbital period is given, as well as ...

The Apparently Decaying Orbit of WASP-12 [PDF]
, 2017 We present new transit and occultation times for the hot Jupiter WASP-12b. The data are compatible with a constant period derivative: $\dot{P}=-29 \pm 3$ ms yr$^{-1}$ and $P/\dot{P}= 3.2$ Myr.
