Rediscovering the observations of solar prominences from 1906 to 1957 recorded at the Madrid Astronomical Observatory

open access: yesJournal of Space Weather and Space Climate, 2023
The Madrid Astronomical Observatory implemented a solar observation program from 1876 to 1986. In addition to sunspots, the observers at this observatory recorded other solar features such as prominences.

A note on the sunspot and prominence records made by Angelo Secchi during the period 1871–1875

open access: yesJournal of Space Weather and Space Climate, 2021
Angelo Secchi (1818–1878) was an Italian Jesuit who made relevant scientific contributions in geophysics, meteorology, and astrophysics. He was a well-known pioneer in solar physics due to his theories and observations.

Paying for Prominence [PDF]

open access: yesThe Economic Journal, 2011
We investigate three ways in which firms can become "prominent" and thereby influence the order in which consumers consider options. First, firms can affect an intermediary's sales efforts by means of commission payments. When firms pay commission to a salesman, the salesman promotes the product with the highest commission, and steers ignorant ...

Prominence Eruptions [PDF]

open access: yesInternational Astronomical Union Colloquium, 1998
AbstractThe kinematics and dynamics of prominence eruptions are reviewed and different phases of the eruption are identified. The properties of the equation of motion in these phases are shown. The morphology of the prominence prior and during the eruption is described and the implications to the MHD description of the process are discussed.

Co- and counter-helicity interaction between two adjacent laboratory prominences [PDF]

open access: yes, 2004
The interaction between two side-by-side solar prominence-like plasmas has been studied using a four-electrode magnetized plasma source that can impose a wide variety of surface boundary conditions.

Automatic detection of limb prominences in 304 A EUV images [PDF]

open access: yes, 2009
A new algorithm for automatic detection of prominences on the solar limb in 304 A EUV images is presented, and results of its application to SOHO/EIT data discussed.

Dissipative instability in partially ionised prominence plasmas [PDF]

open access: yes, 2015
We investigate the nature of dissipative instability at the boundary (seen here as tangential discontinuity) between the viscous corona and the partially ionised prominence plasma in the incompressible limit.

RA-induced prominence-specific response resulted in distinctive regulation of Wnt and osteogenesis

open access: yesLife Science Alliance, 2023
Early exposure of RA induced altered expressions of Wnt-related genes and subsequent osteogenic differentiation in embryonic mouse craniofacial prominences in a spatiotemporal-dependent manner.

Solar prominence modelling and plasma diagnostics at ALMA wavelengths [PDF]

open access: yes, 2017
Our aim is to test potential solar prominence plasma diagnostics as obtained with the new solar capability of the Atacama Large Millimeter / submillimeter Array (ALMA).
