PRAIA–Package for the Reduction of Astronomical Images Automatically–is a suite of
astrometric and photometric tasks designed to cope with huge amounts of heterogeneous …

In general, astronomical images are made by the charge-coupled device (CCD)[Smith 2010]
or other cameras/sensors. Also, such astronomical images can be received from other …

Context. Since July 2014, the Gaia mission of the European Space Agency has been
surveying the entire sky down to magnitude 20.7 in the visible. In addition to the millions of …

Soon after the discovery of asteroid 99942 Apophis, it was classified as a potentially
hazardous object with a high probability of an impact on the Earth in 2029. Although …

Abstract Space-based telescopes offer unparalleled opportunities for characterizing
exoplanets, solar system bodies, and stellar objects. However, observatories in low-Earth …

The 80 cm azimuthal telescope has newly been mounted at Yaoan Station, Purple Mountain
Observatory since 2018. The astrometric performance of the telescope is tested in the …

We investigate the surface thermophysical properties (thermal emissivity, thermal inertia,
roughness fraction and geometric albedo) of asteroid (99942) Apophis, using the currently …

Abstract Trans-Neptunian objects (TNOs) are a source of invaluable information to access
the history and evolution of the outer solar system. However, observing these faint objects is …

The rotational reflex velocity (RRV) method was proposed by Heinze and Metchev in 2015
and was used to measure the distances of main-belt asteroids (MBAs). Later, Lin et al …

Predicting the motion of near-Earth asteroids (NEAs) is a complex task that requires the use
of sophisticated technology, various techniques, and significant computational resources. In …
