Ph.D. student Omair Zubairi heads off to Storrs, CT & Boston, MA for two conferences where he is presenting his work involving Numerical Astrophysics of Compact Stars. The IARD (International Association of Relativistic Dynamics) is holding their biannual conference at University of Connecticut. Omair Zubairi will presenting his recent work on Non-Spherical Models of Compact Stars along with Solutions of Einstein’s Field equations modified for the Cosmological Constant.

See Below for his abstract:

In this work, we present two solutions of Einstein’s field equations for compact stellar objects such as neutron or quark stars. Due to their unique stellar properties, these compact objects pose as excellent laboratories to study matter in the most extreme conditions. The first scenerio, we solve Einstein’s field equations modified for a finite value for the cosmological constant for spherically symmetric mass distributions–i.e. Compact Stars. We present a full 1-D model of the global stellar structure of these compact objects in the framework of general relativity modified for a cosmological constant. This solution has been presented in literature before, but with inconsistent results. The second solution we present examines the deformation of compact objects such as magnetars and neutron stars with color superconducting quark matter cores. Due to their extremely high magnetic fields, these two certain classes of compact stellar objects are expected to be deformed (non-spherical) making them oblong spheroids. Due to this deformity, the stellar structure equations of these objects must be re-derived. We present another full 1-D model of the global stellar structure of these compact objects in this framework–in the limiting case of isotropic pressure and energy-density. We calculate stellar properties such as mass, radii, along with pressure and density profiles for these deformed objects and investigate changes from the standard spherical models.

Omair Zubairi is also will be presenting a unique talk at the annual Polytechnic Conference held this year at Wentworth Institutue of Technology in Boston, MA, where he is presenting a talk titled: “Computational Science and its Applications: An Interdisciplinary Collaboration Among Scientists.” this talk is focused on exposing the Computational Science degree program to a various consortium of educators, scientists, and administrators.

Over the last 30 years, the scientific world has evolved from mere handwritten concepts to high performance computing. Scientists in all fields from biology to theoretical physics all use some type of computational skills to perform research. The advancements of research requires the collaboration of scientists, engineers, mathematicians, and computer scientists from all different fields, all tied together with the computing skills needed to perform calculations of any magnitude. In this talk, I will discuss a recently developed degree program known as Computational Science. I will discuss how this interdisciplinary degree program helps our current scientific community by allowing scientists from different fields to collaborate with each other on various research fronts. Due to advancements in technology and computing, no classroom is the same as before. I will also discuss, how this program positively impacts students from all disciplines in the scientific world and helps them prepare them for the jobs of tomorrow.
