Here are some examples of current (and previous) research opportunities that involve undergraduate and graduate students. These projects use analytical and 1d, 2d, or 3d numerical techniques. They all have significant room for developing Senior, M.S. or Ph.D. theses by talented undergraduate or graduate students at Arizona State University. In addition to the links below, prospective students might want to peruse the links given on the menu to the left.

Thermonuclear Supernova:

Effects in simmering phase of Type Ia Supernova

Ignition in Type Ia supernova

Laminar flame speedup by ²²Ne

Variations in the peak brightness of Type Ia supernova from metallicity

Growing white dwarfs to Type Ia Supernova

Sedimentation of ²²Ne in white dwarfs

Density dependence of ⁵⁶Ni ejected by Type Ia supernovae

Merger of two white dwarfs merging as a progenitor system thermonuclear supernova.

Core-Collapse Supernova:

Nucleosynthesis of fallback

²⁶Al and ⁶⁰Fe from core-collapse models (a prediction verified!)

⁴⁴Ti and ⁵⁶Ni from core-collapse models

Proton rich nuclear statistical equilibrium

Convection in Oxygen & Silicon Shell Burning

Stellar Evolution:

Helium shell flash convection

MESA Modules for Experiments in Stellar Astrophysics

NUGRID Astrophysical Nuclear Yields Grid collaboration.

A new survey of abundance yields from massive stars (with Prof. Patrick Young at ASU)

Convection in Classical Nova Systems (with Prof. Sumner Starfield at ASU)

Verification:

Verification of hydrocodes

Complete Sedov-Taylor blast wave solution code & paper

Complete calculation verification graphs and paper

Thermodynamics:

Develop a Gibbs free energy equation of state for stellar environments

Chemical Evolution:

Classical mean-field zone models

Investigate the self-enrichment of stellar clusters (with Prof. Evan Scannapieco at ASU)

Create chemodynamic models of the Milky Way's enrichment history

Astrobiology:

Adapt the ODE integration technology for nuclear reaction networks to chemical reaction networks

Chemistry during planetary system formation (with Prof. Steve Desch at ASU).

Investigate variation of element and chemical abundances in habitable systems
