DOI: 10.1007/s12206-017-1007-2
Abstract: We performed numerical simulations to study the flow characteristic in a centrifugal pump based on the RANS equations and the RNG k-ε turbulent model. The flow field, including the front and back pump chambers, the… read more here.

DOI: 10.1051/0004-6361/201630073
Abstract: Co-orbital planets have not yet been discovered, although they constitute a frequent by-product of planetary formation and evolution models. This lack may be due to observational biases, since the main detection methods are unable to… read more here.

DOI: 10.1051/0004-6361/201732156
Abstract: The identification and characterisation of low-mass binaries is of importance for a range of astrophysical investigations. Low-mass binaries in young (∼10–100 Myr) moving groups (YMGs) in the solar neighborhood are of particular significance as they… read more here.

DOI: 10.1051/0004-6361/201936389
Abstract: Twenty-four years after the discoveries of the first exoplanets, the radial-velocity (RV) method is still one of the most productive techniques to detect and confirm exoplanets. But stellar magnetic activity can induce RV variations large… read more here.
