Asteroseismic Investigation of Known Planet Hosts in the Kepler Field

, 2009
In addition to its great potential for characterizing extra-solar planetary systems the Kepler mission is providing unique data on stellar oscillations.

New analytical and numerical models of solar coronal loop: I. Application to forced vertical kink oscillations

, 2014
Aims. We construct a new analytical model of a solar coronal loop that is embedded in a gravitationally stratified and magnetically confined atmosphere. On the basis of this analytical model, we devise a numerical model of solar coronal loops.

The solar oscillations spectrum and the solar cycle [PDF]

Symposium - International Astronomical Union, 1988
During the summer seasons of the years 1977 to 1985 daily velocity measurements of solar global oscillations have been obtained using a resonant scattering spectrometer. After calculating the power spectra of the daily residuals, the mean for each season is found.

Implications of CHOOZ results for the decoupling of solar and atmospheric neutrino oscillations

, 1998
We have considered the results of solar and atmospheric neutrino oscillation experiments in the scheme of mixing of three neutrinos with a mass hierarchy.

Solar Neutrinos Before and After KamLAND [PDF]

, 2002
We use the recently reported KamLAND measurements on oscillations of reactor anti-neutrinos, together with the data of previously reported solar neutrino experiments, to show that: (1) the total 8B neutrino flux emitted by the Sun is 1.00(1.0 \pm 0.06 ...

The n−n¯ oscillations in neutron fluxes running from Sun to Earth

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The process of n−n¯ oscillations in the solar cosmic-rays is considered. It is shown that it has high intensity with respect to the analogic processes on the Earth (Ic−r/IEarth∝108), because magnetic field strongly suppresses n−n¯ oscillations. Energetic

Information-theoretic Analysis of Longitude Distribution of Photospheric Magnetic Fields from MDI/HMI Synoptic Maps: Evidence for Rossby Waves

The Astrophysical Journal, 2023
Much of the research on the magnetic activity of the Sun has been focused on its axisymmetric component. However, the longitudinal complexity plays a fundamental role in the solar magnetic activity.

Atmospheric, Solar, and CHOOZ neutrinos: a global three generation analysis [PDF]

, 2001
We perform a global three generation analysis of the current solar and atmospheric evidence in favor of neutrino oscillations. We also include the negative results coming from CHOOZ to constrain the nu_e mixing.

Nonzero Phase Shifts of Acoustic Waves in the Lower Solar Atmosphere Measured from Realistic Simulations and Their Role in Local Helioseismology

The Astrophysical Journal, 2023
Previous studies analyzing the evanescent nature of acoustic waves in the lower solar atmosphere, up to 300 km above the photosphere, have shown an unexpected phase shift of an order of 1 s between different heights.
