A photometric and spectroscopic survey of solar twin stars within 50 parsecs of the Sun: I. Atmospheric parameters and color similarity to the Sun
G. F. Porto de Mello, R. da Silva, L. da Silva +1
Solar twins and analogs are fundamental in the characterization of the Sun's place in the context of stellar measurements, as they are in understanding how typical the solar proper…
Single Past Null Geodesic in the Lemaitre-Tolman-Bondi Cosmology
Felipe A. M. G. Nogueira
This work provides a general discussion of the spatially inhomogeneous Lemaître-Tolman-Bondi (LTB) cosmology, as well as its basic properties and many useful relevant quantities, s…
Nova Centauri 2013 broad maximum from visual observations calibrated with same altitude stars
Costantino Sigismondi
A bright Nova in Centaurus was discovered on Dec 2, 2013 at magnitude V=5.5. Its luminosity reached mv=3.8 from Dec 5 to 7, becoming the brightest Nova of 2013 and of the last deca…
Unveiling the Structure of Barred Galaxies at 3.6 with the Spitzer Survey of Stellar Structure in Galaxies (SG): I. Disk Breaks
Taehyun Kim, Dimitri A. Gadotti, Kartik Sheth +24
We have performed two-dimensional multicomponent decomposition of 144 local barred spiral galaxies using 3.6 images from the Spitzer Survey of Stellar Structure in Galax…
ARRAKIS: Atlas of Resonance Rings As Known In the S4G
S. Comerón, H. Salo, E. Laurikainen +19
Resonance rings are the consequence of secular evolution processes that redistribute material and angular momentum in discs. We produced a Catalogue and an Atlas of the rings detec…
Spatially resolved physical and chemical properties of the planetary nebula NGC 3242
H. Monteiro, D. R. Gonçalves, M. L. Leal-Ferreira +1
Optical integral-field spectroscopy was used to investigate the planetary nebula NGC 3242. We analysed the main morphological components of this source, including its knots, but no…
