Carbon-oxygen ultra-massive white dwarfs in general relativity
Leandro G. Althaus, Alejandro H. Córsico, María E. Camisassa +4
We employ the La Plata stellar evolution code, LPCODE, to compute the first set of constant rest-mass carbon-oxygen ultra-massive white dwarf evolutionary sequences for masses high…
The Puzzling Structure of Solar Convection: Window into the Dynamo
Nicholas A. Featherstone, Kyle C. Augustson, Jonathan M. Aurnou +25
The operation of the solar dynamo, with all of its remarkable spatio-temporal ordering, remains an outstanding problem of modern solar physics. A number of mechanisms that might pl…
Newtonian pulsations of relativistic ONe-core ultra-massive DA white dwarfs
Alejandro H. Córsico, Leandro G. Althaus, María E. Camisassa
Ultra-massive H-rich (DA spectral type) white dwarf stars () are expected to be substantially crystallized by the time they reach the ZZ Ceti instabilit…
Structure and evolution of ultra-massive white dwarfs in general relativity
L. G. Althaus, M. E. Camisassa, S. Torres +4
We present the first set of constant rest-mass ultra-massive oxygen/neon white dwarf cooling tracks with masses larger than 1.29 Msun which fully take into account the effects of g…
Solar-like to Antisolar Differential Rotation: A Geometric Interpretation
Maria E. Camisassa, Nicholas A. Featherstone
The solar convection zone rotates differentially, with its equatorial region rotating more rapidly than the polar regions. This form of differential rotation, also observed in many…
Can we reveal the core-chemical composition of ultra-massive white dwarfs through their magnetic fields?
Maria E. Camisassa, Roberto Raddi, Leandro G. Althaus +5
Ultra-massive white dwarfs () are particularly interesting objects that allow us to study extreme astrophysical phenomena such as type Ia superno…
