Three generations of stars: a possible case of triggered star formation
Evidence for triggered star formation linking three generations of stars is difficult to assemble, as it requires convincingly associating evolved massive stars...
Three hot Jupiters transiting K-dwarfs with significant heavy element masses
Context. Despite predictions from planetary population synthesis models indicating that such systems should be exceedingly rare, short-period gas giants do...
Three Long-period Transiting Giant Planets from TESS
We report the discovery and orbital characterization of three new transiting warm giant planets. These systems were initially identified as presenting single...
Three Lyman-α-emitting filaments converging to a massive galaxy group at z = 2.91: discussing the case for cold gas infall
We have discovered a 300 kpc-wide giant Lyman-α (Lyα) nebula centered on the massive galaxy group RO-1001 at z = 2.91 in the Cosmic Evolution Survey field. Keck...
Three new 2+2 quadruple systems with changing inclination
We present a unique discovery of three new detected systems showing two different phenomena together. These are 2+2 quadruple stellar systems showing two...
Three new young objects from the IRAS Point Source Catalogue
Three new young objects have been found when carrying out a survey of IRAS sources with infrared colors like planetary nebulae, via low resolution spectroscopy...
Three planets transiting the evolved star EPIC 249893012: a hot 8.8-M<SUB>⊕</SUB> super-Earth and two warm 14.7 and 10.2-M<SUB>⊕</SUB> sub-Neptunes
We report the discovery of a new planetary system with three transiting planets, one super-Earth and two sub-Neptunes, that orbit EPIC 249893012, a G8 IV-V...
We present three giant stars from the ongoing Penn State–Toruń Planet Search with the Hobby–Eberly Telescope, which exhibit radial velocity (RV) variations that...
