Analysis of Selected Runaway Stars in the Orion Nebula Based on Data from the Gaia EDR3 Catalogue
Bobylev, V. V.; Bajkova, A. T.
We have performed Monte Carlo simulations of the trajectories of several runaway stars using their parallaxes and proper motions from the Gaia EDR3 catalogue. We have confirmed the hypothesis that the stars AE Aur and $µ$ Col are a product of the multiple system breakup ${∼}2.5$ Myr ago and the Orion Trapezium may be the parent cluster for t…
Orbits of Visual Double Stars from P. Couteau's Catalogue Determined with Gaia DR2 and Gaia EDR3 Data
Kisser, A. E.; Krechet, V. G.
The orbits of ten stars discovered by P. Couteau have been determined for the first time: COU 99, 357, 610, 850, 1346, 1531, 1642, 1752, 1845, and 2459. For two of them (COU 850 and 1752) an arc of more than half a revolution is covered by observations; the orbits of the remaining stars have been determined from short arcs ($5^{\circ}{-}50^{\circ}…
