Newly identified compact hierarchical triple system candidates using Gaia DR3
Donát R. Czavalinga, Tibor Mitnyan, Saul A. Rappaport +5
Aims. We introduce a novel way to identify new compact hierarchical triple stars by exploiting the huge potential of Gaia DR3 and also its future data releases. We aim to increase…
Lost in space: companions' fatal dance around massive dying stars
Zsolt Regaly, Viktoria Frohlich, Jozsef Vinko
Discoveries of planet- and stellar remnant-hosting pulsars challenge our understanding as the violent supernova explosion that forms the pulsar presumably destabilizes the system.…
Mid-infrared time-domain study of recent dust production events in the extreme debris disc of TYC 4209-1322-1
A. Moór, P. Ábrahám, Á. Kóspál +23
Extreme debris discs are characterized by unusually strong mid-infrared excess emission, which often proves to be variable. The warm dust in these discs is of transient nature and…
KIC 7955301: a hierarchical triple system with eclipse timing variations and an oscillating red giant
P. Gaulme, T. Borkovits, T. Appourchaux +13
KIC 7955301 is a hierarchical triple system with eclipse timing and depth variations discovered by the Kepler mission. It is composed of a non-eclipsing primary star at the bottom…
TIC 114936199: A Quadruple Star System with a 12-day Outer Orbit Eclipse
Brian P. Powell, Saul A. Rappaport, Tamás Borkovits +19
We report the discovery with TESS of a remarkable quadruple star system with a 2+1+1 configuration. The two unique characteristics of this system are that (i) the inner eclipsing b…
Von Zeipel - Lidov - Kozai cycles in action: triples with eclipse depth variations: KICs 6964043, 5653126, 5731312 and 8023317
T. Borkovits, S. A. Rappaport, S. Toonen +3
We report the results of the photodynamical analyses of four compact, tight triple stellar systems, KICs 6964043, 5653126, 5731312, 8023317, based largely on and da…
