Solar inertial modes: Observations, identification, and diagnostic promise
Laurent Gizon, Robert H. Cameron, Yuto Bekki +10
The oscillations of a slowly rotating star have long been classified into spheroidal and toroidal modes. The spheroidal modes include the well-known 5-min acoustic modes used in he…
Observations of large-scale solar flows
Bastian Proxauf
In this dissertation, several components of large-scale solar flows are studied observationally: solar equatorial Rossby waves (waves of radial vorticity), large-scale convection,…
Exploring the latitude and depth dependence of solar Rossby waves using ring-diagram analysis
B. Proxauf, L. Gizon, B. Löptien +3
Global-scale Rossby waves have recently been unambiguously identified on the Sun. Here we study the latitude and depth dependence of the Rossby wave eigenfunctions. By applying hel…
Global-scale equatorial Rossby waves as an essential component of solar internal dynamics
Björn Löptien, Laurent Gizon, Aaron C. Birch +5
The Sun's complex dynamics is controlled by buoyancy and rotation in the convection zone and by magnetic forces in the atmosphere and corona. While small-scale solar convection is…
On a new and homogeneous metallicity scale for Galactic classical Cepheids - I. Physical parameters
B. Proxauf, R. da Silva, V. V. Kovtyukh +23
We gathered more than 1130 high-resolution optical spectra for more than 250 Galactic classical Cepheids. The spectra were collected with different optical spectrographs: UVES at V…
On the chemical abundances of Miras in clusters: V1 in the metal-rich globular NGC 5927
V. D'Orazi, D. Magurno, G. Bono +50
We present the first spectroscopic abundance determination of iron, alpha-elements (Si, Ca and Ti) and sodium for the Mira variable V1 in the metal-rich globular cluster NGC 5927.…
