Gravitational Helioseismology? [PDF]
Physical Review D, 1996 The magnitudes of the external gravitational perturbations associated with the normal modes of the Sun are evaluated to determine whether these solar oscillations could be observed with the proposed Laser Interferometer Space Antenna (LISA), a network of

, 1992 The observed deficit of $\rm ^8B$ solar neutrinos may call for an improved standard model of the sun or an expanded standard model of particle physics ({\it e.g.,} with neutrino masses and mixing).

Bulletin de la Société Royale des Sciences de Liège, 2019 Helioseismology is one of the most successful fields of astrophysics. The observation and character-ization of solar oscillation has allowed solar seismologists to study the internal structure and dynamics of the Sun with unprecedented thoroughness. Ground-based networks and dedicated space missions have delivered data of exquisite quality, enabling ...

The Phanerozoic climate. [PDF]
Ann N Y Acad Sci, 2023 We review the long‐term climate variations during the last 540 million years (Phanerozoic Eon). We first summarize the geological and geochemical datasets available for reconstruction of long‐term climate variations. We then explore the main drivers of climate that appear to explain a large fraction of these climatic oscillations. The first is the long‐

Helioseismology with PICARD [PDF]
Journal of Physics: Conference Series, 2013 PICARD is a CNES micro-satellite launched in June 2010 (Thuillier at al. 2006). Its main goal is to measure the solar shape, total and spectral irradiance during the ascending phase of the activity cycle. The SODISM telescope onboard PICARD also allows us to conduct a program for helioseismology in intensity at 535.7 nm (Corbard et al. 2008).

Radial gradient of the solar rotation rate in the near-surface shear layer of the Sun
Frontiers in Astronomy and Space Sciences, 2022 We study the radial gradient of the solar rotation rate in the near-surface shear layer (NSSL) from about .950 R⊙ to the solar surface and its variation during Solar Cycles 23 and 24 with ring-diagram analysis applied to Global Oscillation Network Group (

Equatorially trapped Rossby waves in radiative stars
Astronomische Nachrichten, Volume 344, Issue 10, December 2023., 2023 Abstract Observations by recent space missions reported the detection of Rossby waves (r‐modes) in light curves of many stars (mostly A, B, and F spectral types) with outer radiative envelope. This article aims to study the theoretical dynamics of Rossby‐type waves in such stars. Hydrodynamic equations in a rotating frame were split into horizontal and
