Gaia search for stellar companions of TESS Objects of Interest II
Mugrauer, Markus; Michel, Kai-Uwe
We present the latest results of our ongoing multiplicity study of (Community) TESS Objects of Interest, using astro- and photometric data from the ESA-Gaia mission, to detect stellar companions of these stars and to characterize their properties. In total, 107 binary, 5 hierarchical triple star systems, as well as one quadruple system were detect…
Jet‑triggered star formation in young radio galaxies
Baum, Stefi; Morganti, Raffaella; Tremblay, Grant +7 more
Emission in the ultraviolet continuum is a salient signature of the hot, massive and consequently short-lived, stellar population that traces recent or ongoing star formation. With the aim of mapping star forming regions and morphologically separating the generic star formation from that associated with the galaxy-scale jet activity, we obtained h…
