Exact Scalar-Tensor Cosmological Models
J. A. Belinchón, T. Harko, M. K. Mak
Scalar-tensor gravitational theories are important extensions of standard general relativity, which can explain both the initial inflationary evolution, as well as the late acceler…
Six winters of photometry from Dome C, Antarctica: challenges, improvements, and results from the ASTEP experiment
N. Crouzet, D. Mékarnia, T. Guillot +26
ASTEP (Antarctica Search for Transiting ExoPlanets) is a pilot project that aims at searching and characterizing transiting exoplanets from Dome C in Antarctica and to qualify this…
The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. VIII. Preliminary Public Catalog Release
M. Soto, A. Bellini, J. Anderson +14
The Hubble Space Telescope (HST) UV Legacy Survey of Galactic Globular Clusters (GO-13297) has been specifically designed to complement the existing F606W and F814W observations of…
Extension of a factorization method of nonlinear second order ODE's with variable coefficients
H. C. Rosu, O. Cornejo-Perez, M. Perez-Maldonado +1
The factorization of nonlinear second-order differential equations proposed by Rosu and Cornejo-Perez in 2005 is extended to equations containing quadratic and cubic forms in the f…
Structure of radiation dominated gravitoturbulent quasar discs
Mohsen Shadmehri, Fazeleh Khajenabi, Sami Dib
Self-gravitating accretion discs in a gravitoturbulent state, including radiation and gas pressures, are studied using a set of new analytical solutions. While the Toomre parameter…
Jacobi stability analysis of scalar field models with minimal coupling to gravity in a cosmological background
Bogdan Dănilă, Tiberiu Harko, Man Kwong Mak +2
We perform the study of the stability of the cosmological scalar field models, by using the Jacobi stability analysis, or the Kosambi-Cartan-Chern (KCC) theory. In the KCC approach…
The Bok Globule BHR 160: structure and star formation
Lauri K Haikala, Bo Reipurth
BHR 160 is a virtually unstudied cometary globule within the Sco OB4 association in Scorpius at a distance of 1600pc. It is part of a system of cometary clouds which face the lumin…
Intensity Interferometry with Aqueye+ and Iqueye in Asiago
L. Zampieri, G. Naletto, C. Barbieri +6
Since a number of years our group is engaged in the design, construction and operation of instruments with very high time resolution in the optical band for applications to Quantum…
Hybrid metric-Palatini stars
Bogdan Danila, Tiberiu Harko, Francisco S. N. Lobo +1
We consider the internal structure and the physical properties of specific classes of neutron, quark and Bose-Einstein Condensate stars in the hybrid metric-Palatini gravity theory…
Olivine on Vesta as exogenous contaminants brought by impacts: Constraints from modeling Vesta's collisional history and from impact simulations
D. Turrini, V. Svetsov, G. Consolmagno +2
The survival of asteroid Vesta during the violent early history of the Solar System is a pivotal constraint on theories of planetary formation. Particularly important from this per…
Exact power series solutions of the structure equations of the general relativistic isotropic fluid stars with linear barotropic and polytropic equations of state
T. Harko, M. K. Mak
Obtaining exact solutions of the spherically symmetric general relativistic gravitational field equations describing the interior structure of an isotropic fluid sphere is a long s…
Massive stars reveal variations of the stellar initial mass function in the Milky Way stellar clusters
Sami Dib, Stefan Schmeja, Sacha Hony
We investigate whether the stellar initial mass function (IMF) is universal, or whether it varies significantly among young stellar clusters in the Milky Way. We propose a method t…
Hi-GAL, the Herschel infrared Galactic Plane Survey: photometric maps and compact source catalogues. First data release for Inner Milky Way: +68°> l > -70°
S. Molinari, E. Schisano, D. Elia +62
(Abridged) We present the first public release of high-quality data products (DR1) from Hi-GAL, the {\em Herschel} infrared Galactic Plane Survey. Hi-GAL is the keystone of a suite…
Interacting supernovae and supernova impostors. LSQ13zm: an outburst heralds the death of a massive star
L. Tartaglia, A. Pastorello, M. Sullivan +37
We report photometric and spectroscopic observations of the optical transient LSQ13zm. Historical data reveal the presence of an eruptive episode (that we label as `2013a') followe…
Asteroid 4 Vesta: dynamical and collisional evolution during the Late Heavy Bombardment
S. Pirani, D. Turrini
Vesta is the only currently identified asteroid for which we possess samples, which revealed us that the asteroid is differentiated and possesses a relatively thin basaltic crust t…
