Solar System Ephemerides, Pulsar Timing, Gravitational Waves, and Navigation
, 2017 In-spiraling supermassive black holes should emit gravitational waves, which would produce characteristic distortions in the time of arrival residuals from millisecond pulsars.

New orbital ephemerides for the dipping source 4U 1323-619: constraining the distance to the source [PDF]
, 2016 4U 1323-619 is a low mass X-ray binary system that shows type I X-ray bursts and dips. The most accurate estimation of the orbital period is 2.941923(36) hrs and a distance from the source that is lower than 11 kpc has been proposed. We aim to obtain the

Ecology and Evolution, Volume 15, Issue 12, December 2025.Study comprises the first field study of the flight altitude of the common crane (Grus grus) during seasonal migrations across the Baltic Sea. Our investigations clearly indicate that despite weather‐induced variations in the flight altitude, the majority of cranes will cross the Baltic Sea at altitudes between 50 and 250 m.

S/W Development of High Precesion EPHEMERIS(I) [PDF]
Journal of Astronomy and Space Sciences, 1993 We developed the S/W which calculate the Planetary and the Moon ephemerides. The ephemeris of the Solar system objects was obtained from a simultaneous numerical integration of the equations of motion for the nine planets and the Moon.

Jupiter's X‐ray Aurorae. A High Signal Spectral Analysis of the 0.24–1.40 keV Energy Range
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract Jupiter's X‐ray auroras are predominantly produced by precipitating energetic heavy ions. Recent results suggest a connection between the pulsation rate of these ion aurorae and the pulsation rate of magnetospheric waves. Using remote X‐ray observations and results from in situ measurements from the Juno Jupiter Energetic particle Detector ...

Serbian Astronomical Journal, 2004 In this paper the orbits of binaries WDS 10093+2020 = A 2145, WDS 21074-0814 = BU 368 AB and WDS 22288-0001 = STF 2909 AB are recalculated because of significant deviations of more recent observations from the ephemerides. For binaries WDS 22384-0754 = A

Gravitational solution to the Pioneer 10/11 anomaly
, 2005 A fully relativistic modified gravitational theory including a fifth force skew symmetric field is fitted to the Pioneer 10/11 anomalous acceleration. The theory allows for a variation with distance scales of the gravitational constant G, the fifth force

Multiwavelength transit observations of the candidate disintegrating planetesimals orbiting WD 1145+017 [PDF]
, 2015 We present multiwavelength, ground-based follow-up photometry of the white dwarf WD 1145+017, which has recently been suggested to be orbited by up to six or more short-period, low-mass, disintegrating planetesimals.
