Origin of the Structure of the Kuiper Belt during a Dynamical Instability in the Orbits of Uranus and Neptune
Harold F. Levison, Alessandro Morbidelli, Christa Van Laerhoven +2
We explore the origin and orbital evolution of the Kuiper belt in the framework of a recent model of the dynamical evolution of the giant planets, sometimes known as the Nice model…
Taxonomy of asteroid families among the Jupiter Trojans: Comparison between spectroscopic data and the Sloan Digital Sky Survey colors
F. Roig, A. O. Ribeiro, R. Gil-Hutton
We present a comparative analysis of the spectral slope and color distributions of Jupiter Trojans, with particular attention to asteroid families. We use a sample of data from the…
Carbon abundances of early B-type stars in the solar vicinity. Non-LTE line-formation for C II/III/IV and self-consistent atmospheric parameters
M. F. Nieva, N. Przybilla
Precise determinations of the chemical composition in early B-type stars consitute fundamental observational constraints on stellar and galactochemical evolution. Carbon is one of…
Dense gas in luminous infrared galaxies
W. A. Baan, C. Henkel, A. F. Loenen +2
Molecules that trace the high-density regions of the interstellar medium have been observed in (ultra-)luminous (far-)infrared galaxies, in order to initiate multiple-molecule mult…
Observational constraints on late-time Lambda(t) cosmology
S. Carneiro, M. A. Dantas, C. Pigozzo +1
The cosmological constant, i.e., the energy density stored in the true vacuum state of all existing fields in the Universe, is the simplest and the most natural possibility to desc…
The Ultraviolet Spectra of the Weak Emission Line Central Stars of Planetary Nebulae
W. L. F. Marcolino, F. X. de Araujo, H. B. M. Junior +1
The ultraviolet spectra of all ``weak emission line central stars of planetary nebulae'' (WELS) with available IUE data are presented and discussed. We performed line identificatio…
