1. Uma super equipe para a nova Ramb - Wajngarten,Maurício

2. Super-NOvA: a long-baseline neutrino experiment with two off-axis detectors - Requejo, Olga Mena; Palomares-Ruiz, Sergio; Pascoli, Silvia
Establishing the neutrino mass hierarchy is one of the fundamental questionsthat will have to be addressed in the next future.

3. A Modeling of the Super-Eddington Luminosity in Nova Outbursts: V1974 Cygni - Kato, Mariko; Hachisu, Izumi
We have modeled nova light curves exceeding the Eddington luminosity.

4. NOSTOS experiment and new trends in rare event detection - Giomataris, I.; Aune, S.; Colas, P.; Irastorza, I.; Peyaud, B.; Dolbeau, J.; Gorodetzky, P.; van der Graff, H.; Patzak, T.; Salin, P.; Lepeltier, V.; Vergados, J. D.
A novel low-energy neutrino-oscillation experiment NOSTOS, combining a strongtritium source and a high pressure spherical TPC detector (10 m in radius) hasbeen recently proposed.

5. Inflaton field governed universe from NKK theory of gravity: stochastic approach - Anabitarte, Mariano; Aguilar, Jose Edgar Madriz; Bellini, Mauricio
We conclude that the inflaton field has been sliding down its(quadratic) potential hill along all the evolution of the universe and a massof the order of the Hubble parameter.

6. Characteristic Temperatures in Super-Novae - Zwicky, F.
These temporary objects are individual stars which behave like giant analogues of common novae and which, therefore, may appropriately be called super-novae.

7. Rates of neutrino conversion and decay in hot and dense QED plasma - Asida, N.; Niégawa, A.; Ozaki, H.; Kubota, M.
Using a real-time formalism of equilibrium and nonequilibrium quantum-fieldtheory, we derive the reaction-rate formula for neutrino-conversion ($\nu \to\nu'$) process and $\nu \bar{\nu}'$ annihilation process, which take place in ahot and dense QED plasma with background (anti)neutrinos out of equilibrium.

8. Quintessence From a Decaying Dark Matter - Ziaeepour, Houri
It is a known fact that a quintessence model with $w_q < -1$ fits thepublicly available Super Nova (SN) type Ia data better than a model withcosmological constant or $w_q > -1$.

9. (Two) Open Questions in Stellar Nuclear Physics - Gai, Moshe
Accordingly, Nuclear Physicsis presented with two extraordinary challenges: the need for precise (5% orbetter) prediction of solar neutrino fluxes within the Standard Solar Model,and the need for an accurate (5% or better) understanding of stellar evolutionand in particular of Type Ia super nova that are used as cosmological standardcandle.

10. Determining the Neutrino Mass Hierarchy and CP Violation in NOvA with a Second Off-Axis Detector - Mena, Olga; Palomares-Ruiz, Sergio; Pascoli, Silvia
We consider a Super-NOvA-like experimental configuration based on the use oftwo detectors in a long-baseline experiment as NOvA.

11. Time Delay Between Gravitational Waves and Neutrino Burst From a Supernova Explosion: a Test for the Neutrino Mass - Fargion, D.
During Supernova explosions two signals, Gravitational burst wave andNeutrino Burst, of different nature, originated within 0.1 s from thesuper novaexplosion will be radiated in the outer space.

12. How Well Do We Know the Beta-Decay of 16N and Oxygen Formation in Helium Burning - Gai, Moshe
Severalattempts to constrain the p-wave S-factor of the 12C(a,g)16O reaction at Heliumburning temperatures (200 MK) using the beta-delayed alpha-particle emission of16N have been made, and it is claimed that this S-factor is known, as quoted bythe TRIUMF collaboration.

13. A Search for Radio Emission from Supernovae With Ages from About One Week to More Than 80 Years - Eck, Christopher R.; Cowan, John J.; Branch, David
We report VLA radio observations of 29 SNe with ages ranging from 10 days toabout 90 years past explosion.

14. Puzzling afterglow's oscillations in GRBs and SGRs: tails of precessing Jets - Fargion, D.
Damped oscillating afterglows in GRB 030329 and in SGR 1900+14 find a naturalexplanation in precessing gamma Jet model for both GRBs and SGRs.

15. GRBs, Fireballs and Precessing Gamma Jets - Fargion, Daniele
Fireballs are huge isotropic explosions models widely believed to explainGamma Ray Burst, GRBs (Piran,1999); ever-new versions consider wide beamed(10^o) Jet explosions hitting external shells.

16. NOSTOS: a spherical TPC to detect low energy neutrinos - Aune, S.; Colas, P.; Dolbeau, J.; Fanourakis, G.; Ferrer-Ribas, E.; Geralis, T.; Giomataris, Y.; Gorodetzky, P.; Gounaris, G. J.; Irastorza, I. G.; Kousouris, K.; Lepeltier, V.; Patzak, T.; Paschos, E. A.; Salin, P.; Savvidis, I.; Vergados, J. D.
A novel low-energy ($\sim$few keV) neutrino-oscillation experiment NOSTOS,combining a strong tritium source and a high pressure spherical Time ProjectionChamber (TPC) detector 10 m in radius has been recently proposed.

17. Modeling Supernova-like Explosions Associated with Gamma-ray Bursts with Short Durations - Kulkarni, S. R.
By analogy, it has beenpostulated that short-hard bursts originate from neutron star mergers.

18. Nucleonic gamma-ray production in Pulsar Wind Nebulae - Horns, D.; Aharonian, F.; Hoffmann, A. I. D.; Santangelo, A.
Besides shell typesuper-nova remnants, pulsar wind nebulae (PWN) appear to be a dominant sourcepopulation in the catalogue of VHE gamma-ray sources.

19. Classical Novae as Super-Eddington Objects - Shaviv, Nir J.
Several of the inconsistencies plaguing the field of novae are resolved oncewe consider novae to be steady state super-Eddington objects.

20. Adição e avaliação de estímulos sonoros como ferramenta de apoio à exploração visual de dados - Wagner José Franchin
Visualização é o processo genérico que utiliza representações visuais e interativas para facilitar a análise e o entendimento de informações de conjunto de dados.
