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+

Observational Evidence of Shallow Origins for the Magnetic Fields of Solar Cycles

open access: yesFrontiers in Astronomy and Space Sciences, 2018
Observational evidence for the origin of active region magnetic fields has been sought from published information on extended solar cycles, statistical distributions of active regions and ephemeral regions, helioseismology results, positional ...

Inferring the Solar Meridional Circulation Flow Profile by Applying Bayesian Methods to Time–Distance Helioseismology

open access: yesThe Astrophysical Journal, 2023
Mapping the large-scale subsurface plasma flow profile within the Sun has been attempted using various methods for several decades. One such flow in particular is the meridional circulation, for which numerous studies have been published.

Initial Helioseismic Observations by Hinode/SOT [PDF]

open access: yes, 2007
Results from initial helioseismic observations by Solar Optical Telescope onboard Hinode are reported. It has been demonstrated that intensity oscillation data from Broadband Filter Imager can be used for various helioseismic analyses.

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 ...

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.

Global helioseismology (WP4.1): From the Sun to the stars & solar analogs

open access: yesEPJ Web of Conferences, 2017
Sun-as-a star observations put our star as a reference for stellar observations. Here, I review the activities in which the SPACEINN global seismology team (Working Package WP4.1) has worked during the past 3 years. In particular, we will explain the new

Solar Cycle Variations of Rotation and Asphericity in the Near-Surface Shear Layer

open access: yes, 2018
The precise shape of the Sun is sensitive to the influence of gravity, differential rotation, local turbulence and magnetic fields. It has been previously shown that the solar shape exhibits asphericity that evolves with the 11-year cycle.
