We use milli-arcsecond accuracy astrometry (proper motions and parallaxes) from Hipparcos and from radio observations to retrace the orbits of 56 runaway stars and nine compact objects with distances less than 700 pc, to identify the parent stellar group. It is possible to deduce the specific formation scenario with near certainty for two cases. (i) We find that the runaway star ζ Ophiuchi and the pulsar PSR J1932+1059 originated about 1 Myr ago in a supernova explosion in a binary in the Upper… Expand
Analysis of Selected Runaway Stars in the Orion Nebula Based on Data from the Gaia EDR3 Catalogue
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 thatExpand
A nearby recent supernova that ejected the runaway star ζ Oph, the pulsar PSR B1706−16, and 60Fe found on Earth
The detection of ∼1.5–3.2 Myr old 60Fe on Earth indicates recent nearby core-collapse supernovae. For supernovae in multiple stars, the primary stars may become neutron stars, while formerExpand
PG 1610+062: a runaway B star challenging classical ejection mechanisms
Hypervelocity stars are rare objects, mostly main-sequence (MS) B stars, traveling so fast that they will eventually escape from the Milky Way. Recently, it has been shown that the popular HillsExpand
ASTRONOMY AND ASTROPHYSICS On the absence of wind bow-shocks around OB-runaway stars: probing the physical conditions of the interstellar medium
High-resolution IRAS maps are used to search for the presence of stellar-wind bow-shocks around high-mass X-ray binaries (HMXBs). Their high space velocities, recently confirmed with HipparcosExpand
Massive runaway stars in the Small Magellanic Cloud
Using archival Spitzer Space Telescope data, we identified for the first time a dozen runaway OB stars in the Small Magellanic Cloud (SMC) through the detection of their bow shocks. The geometry ofExpand
Low-Mass Runaway Stars from the Orion Trapezium Cluster
In the course of a search for common proper-motion binaries in the Jones & Walker (JW) catalog of proper motions in the Orion Nebula Cluster, we came across several faint stars with proper motionsExpand
No surviving non-compact stellar companion to Cassiopeia A
Massive stars in binaries can give rise to extreme phenomena such as X-ray binaries and gravitational wave sources after one or both stars end their lives as core-collapse supernovae. Stars in closeExpand
A bright early-type star in the halo of NGC 253: Runaway or in situ formation?
We present observations of J004804.8-251749, a blue object in the direction of the halo of NGC 253 with (B −V) = −0.16 ± 0.08, V = 22.09 ± 0.06 and a stellar spectrum showing the Balmer linesExpand
A catalogue of young runaway Hipparcos stars within 3 kpc from the Sun
Traditionally, runaway stars are O- and B-type stars with large peculiar velocities. We would like to extend this definition to young stars (up to ≈50 Myr) of any spectral type and to identify thoseExpand
X-ray counterparts of runaway stars
An X-ray search for possible compact companions of runaway OB stars has been conducted using pointed ROSAT observations. Of a list of 71 runaway stars, ROSAT exposures were available for 24, of whichExpand
