Current Status and Future Prospects of the SNO+ Experiment

open access: yesAdvances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016
SNO+ is a large liquid scintillator‐based experiment located 2 km underground at SNOLAB, Sudbury, Canada. It reuses the Sudbury Neutrino Observatory detector, consisting of a 12 m diameter acrylic vessel which will be filled with about 780 tonnes of ultra‐pure liquid scintillator. Designed as a multipurpose neutrino experiment, the primary goal of SNO+

Stellar Physics and General Relativity

open access: yesAstronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.
ABSTRACT The general theory of relativity is currently established as the most precise theory of gravity supported by observations, and its application is diverse ranging from astronomy to cosmology, while its application to astrophysics has been restricted only to compact stars due to the assumption that the Newtonian approximation is sufficient for ...

Probable Value for the Next Sunspot Minimum

open access: yesAdvances in Astronomy, Volume 2014, Issue 1, 2014., 2014
Gumbel’s first distribution is applied to smoothed monthly mean sunspot numbers for solar cycles 10 to 24. According to that, the next minimum for solar cycle 24‐25 transition would be the deepest solar minimum of the last 150 years. This study provides an additional insight about changes in the Sun which are currently happening.

Toward a Unified Classical model of the Sun: on the Sensitivity of Neutrinos and Helioseismology to the Microscopic Physics

open access: yesThe Astrophysical Journal, 1993
This paper focuses mainly on the neutrino puzzle and discusses the point of view that neutrinos and helioseismology are two complementary probes of the solar interior. We first analyze the physical differences noticed between already published solar models and their consequences for neutrino predictions.

Recent Developments in Degenerate Higher Order Scalar Tensor Theories

open access: yesAnnalen der Physik, Volume 537, Issue 2, February 2025.
Degenerate Higher Order Scalar Tensor theories are reviewed, together with their applications in cosmology and astrophysics. These theories have been applied to build models of the early universe, in the description of the late‐time cosmic acceleration, as well as in astrophysics, including black hole physics. They have the potential to provide answers

Solar Neutrinos

open access: yesAdvances in High Energy Physics, Volume 2013, Issue 1, 2013., 2013
The study of solar neutrinos has given a fundamental contribution both to astroparticle and to elementary particle physics, offering an ideal test of solar models and offering at the same time relevant indications on the fundamental interactions among particles.

Extreme Space Weather Events of the Past 30 Years: Preparation for Data From Mission Vigil

open access: yesEarth and Space Science, Volume 12, Issue 2, February 2025.
Abstract Extreme Space Weather events can negatively affect ground‐based infrastructure and satellite communications. European Space Agency plans to launch a new operational mission, Vigil, to monitor space weather activity and provide timely warnings about immediate danger.

Estimation of Spectral Solar Irradiance in the Ecliptic Plane Using Synthetic Solar Surface Magnetograms

open access: yesJournal of Geophysical Research: Space Physics, Volume 129, Issue 5, May 2024.
Abstract The primary external energy input to planetary atmospheres comes from solar radiation. Accurate estimates of solar irradiance are needed in order to understand atmospheric conditions at other planets. Many studies have interpolated Earth‐based irradiance measurements at other planets, disregarding the evolution of solar features, which are ...
