A PRESENÇA DA FRAGMENTAÇÃO CONSTITUCIONAL NO SENADO GALÁCTICO DA FRANQUIA STAR WARS

Revista de Direito Brasileira, 2022
Na história de Star Wars, em que pese a República Galáctica tenha instituído um ordenamento jurídico universal, há planetas com leis próprias, direitos não-oficiais, em um exemplo claro de pluralismo jurídico. Na contemporaneidade, é possível constatar que, assim como no filme, os atuais modelos de direito não conseguem mais abranger a todos os ...

7Li in Metal-Poor Stars: The Spread of the Li Plateau [PDF]

, 2000
A highly homogeneous study of 23 halo field dwarf stars has achieved a Li abundance accuracy of 0.033 dex per star. The work shows that the intrinsic spread of the Li abundances of these stars at a given metallicity is

The White Dwarfs within 20 Parsecs of the Sun: Kinematics and Statistics [PDF]

, 2009
We present the kinematical properties, distribution of spectroscopic subtypes, stellar population subcomponents of the white dwarfs within 20 pc of the sun. We find no convincing evidence of halo white dwarfs in the total 20 pc sample of 129 white dwarfs

The Top Ten solar analogs in the ELODIE library [PDF]

, 2004
Several solar analogs have been identified in the library of high resolution stellar spectra taken with the echelle spectrograph ELODIE. A purely differential method has been used, based on the chi2 comparison of a large number of G dwarf spectra to 8 ...

MAGNETISM OF WHITE DWARFS (intermediate results of a survey for kilogauss magnetic fields in white dwarfs)

Odessa Astronomical Publications, 2017
We shortly present intermidiate results of a survey for weak magnetic fields among degenerate stars (white dwarfs and hot subdwarf stars). Kilogauss upper limits of longitudinal magnetic fields are presented for several brightest DA white dwarfs and new ...

Asteroseismology of DA white dwarf stars [PDF]

Open Astronomy, 1998
Following the recent mode identification by Clemens suggesting the hydrogen layer mass of the DAV (ZZ Ceti) stars is nearly the same, I make the extreme assumption that models with a single composition profile with a hydrogen layer mass of 1.5 × 10−4M* may be able to fit the observed pulsation periods.

Faint White Dwarf Flux Standards: Data and Models

The Astronomical Journal
Fainter standard stars are essential for the calibration of larger telescopes. This work adds to the calibration spectra (CALSPEC) database of 19 faint white dwarfs (WDs) with all-sky coverage and V magnitudes between 16.5 and 18.7.

Hydrogen Line Shape Uncertainties in White Dwarf Model Atmospheres

Frontiers in Astronomy and Space Sciences, 2022
For isolated white dwarf (WD) stars, fits to their observed spectra provide the most precise estimates of their effective temperatures and surface gravities.

Direct imaging constraints on planet populations detected by microlensing [PDF]

, 2012
Results from gravitational microlensing suggested the existence of a large population of free-floating planetary mass objects. The main conclusion from this work was partly based on constraints from a direct imaging survey.

The HIT Network for Children and Adolescents With CNS Tumors Facilitates Improvements of Diagnostic Assessments, Multimodal Treatments, Individual Counseling, and Research in Germany, Austria, and Switzerland

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The HIT network was established in 2000 to create a population‐based structure aiming to improve survival rates and reduce late effects for children with central nervous system (CNS) tumors by conducting comprehensive clinical trials.
