Third-Order Perturbative Approach to Gravitational Instability: Evolution of Isolated Structures and Environmental Effects
In an Omega 0 = 1 universe, within the classical Eulerian theory of gravitational instability, the redshift evolution of a peculiar velocity field in a region...
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 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...
