Pairs of asteroids sharing similar heliocentric orbits, but not bound together, were found recently. Backward integrations of their orbits indicated that they...
Formation of Fullerenes in H-containing Planetary Nebulae
Hydrogen depleted environments are considered an essential requirement for the formation of fullerenes. The recent detection of C60 and C70 fullerenes in what...
Formation of Kinematic Subsystems in Stellar Spiral-Spiral Mergers
We show that kinematically peculiar cores may be generated in stellar spiral-spiral mergers. Kinematic segregation appears as the central bulges transport...
We present LTE and NLTE results on the formation of LiI lines (λ6103, λ6708, and λ8126) in the atmospheres of solar metallicity dwarfs with effective...
Formation of S0 galaxies through mergers. Antitruncated stellar discs resulting from major mergers <xref ref-type="fn" rid="FN1">
Context. Lenticular galaxies (S0s) are more likely to host antitruncated (Type III) stellar discs than galaxies of later Hubble types. Major mergers are...
Formation of S0 galaxies through mergers. Bulge-disc structural coupling resulting from major mergers
Context. Observations reveal a strong structural coupling between bulge and disc in S0 galaxies, which seems difficult to explain if they have formed from...
Formation of S0 galaxies through mergers. Evolution in the Tully-Fisher relation since z ∼ 1
Context. Lenticular (S0) galaxies are known to derive from spiral galaxies. The fact that S0s nearly obey the Tully-Fisher relation (TFR) at z ∼ 0 (as spirals...
Formation of S0 galaxies through mergers. Explaining angular momentum and concentration change from spirals to S0s
The CALIFA team has recently found that the stellar angular momentum and concentration of late-type spiral galaxies are incompatible with those of lenticular...
Formation of S0 galaxies through mergers. Morphological properties: tidal relics, lenses, ovals, and other inner components
Context. Major mergers are popularly considered too destructive to produce the relaxed regular structures and the morphological inner components (ICs) usually...
