Detailed abundances in stars belonging to ultra-faint dwarf spheroidal galaxies
(2012)
We report preliminary results concerning the detailed chemical composition of metal poor stars belonging to close ultra-faint dwarf galaxies (hereafter UfDSphs). The abundances have been determined thanks to spectra obtained ...
Properties of faintly w-continuous functions
(Boletín de Matemáticas, 2013)
In [3] the authors, introduced the notion of faint !-continuity intopological spaces. In this paper, we investigate new characterizations of this type of continuity.
On upper and lower faintly ω-continuous multifunctions
(Boletín de Matemáticas, 2014-06-26)
The aim of this paper is to introduce and study upper and lower faintly ω-continuous multifunctions as a generalization of upper and lower ω- continuous multifunctions, respectively due to Zorlutuna [7].
Can thin cirrus clouds in the tropics provide a solution to the faint young Sun paradox?
(2010)
In this paper we present radiative-convective simulations to test the idea that tropical cirrus clouds, acting as a negative feedback on climate, can provide a solution to the faint young Sun paradox. We find that global ...
MEASURING SIZES OF ULTRA-FAINT DWARF GALAXIES
(IOP PUBLISHING LTD, 2012-02-01)
The discovery of ultra-faint dwarf (UFD) galaxies in the halo of the Milky Way extends the faint end of the galaxy luminosity function to a few hundred solar luminosities. This extremely low luminosity regime poses a ...
Faint blue objects in the hubble deep field-south revealed: White dwarfs, subdwarfs, and quasars
(Institute of Physics Publishing, 2005)
We explore the nature of the faint blue objects in the Hubble Deep Field-South. We have derived proper motions for the point sources in the Hubble Deep Field-South using a 3 yr baseline. Combining our proper-motion ...
CCD astrometry of faint compact extragalactic radio sources. II.
(2001)
Optical positions relative to the Hipparcos Catalogue (ESA 1997) have been obtained for the optical
counterparts of 28 faint (B 20−23) southern compact extragalactic radio sources (CERS). Most of these sources
are not ...
