NEUTRON STARS

Qualitative behaviour of the magnetic field of a newly-born neutron star. Heras (2016).

Neutron stars are the extremely dense remnants of massive stars after they die and explode as supernovae. These amazing compact remnants have the strongest magnetic fields in the universe (10-1014 G), super high densities (~3 x 1014  g/cm3), very large frequencies (up to 700 Hz), and very high space velocities (up to 1000 km/s!). However, there are still many puzzles about these compact objects. One such a puzzle is to find out how neutron stars receive an intrinsic “kick” at birth, which originates their large space velocities. The research I have done in neutron stars is centered on this specific problem. This is the list of the papers I have written on the subject:

 


RELATIVITY AND ELECTRODYNAMICS

My papers on relativity deal with new approaches for deriving the Lorentz transformations as well as the history of these transformations. On the other hand, the paper I have on electrodynamics deals with a review of the Helmholtz theorem as well as several extentions of this theorem. 


 

PHYSICS TODAY PAPERS

R. Heras, Phys. Today (March 2017)

I have published two papers in Physics Today while still an undergraduate. Both are opinion pieces. The last one being an invited paper with the subject of how I’m being taught physics, and especially, how I would like to be taught physics.  In this commentary, I encourage professors to follow Richard Feynman’s advice to prioritize creative learning in their approach to teaching physics. It is rather unfortunate that physics, which is meant to be an adventure,  is often taught in a very rigid form!
