Three carbon-enhanced metal-poor dwarf stars from the SDSS. Chemical abundances from CO5BOLD 3D hydrodynamical model atmospheres
Context. The origin of carbon-enhanced metal-poor stars enriched with both s and r elements is highly debated. Detailed abundances of these types of stars are...
Three dimensional structure of a regular sunspot from the inversion of IR Stokes profiles
The magnetic, thermal and velocity structure of a regular sunspot, observed close to solar disk center is presented. Spectropolarimetric data obtained with the...
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...
