A Magnetospheric Dichotomy for Pulsars with Extreme Inclinations

Universe, 2021
In this work, we expand on a comment by Lyne et al. (2017), that intermittent pulsars tend to congregate near a stripe in the logarithmic period versus period-derivative diagram.

The Evolutionary Statuses of Solar Type Detached Eclipsing Binary Stars [PDF]

Journal of Astronomy and Space Sciences, 2012
We presented fundamental stellar parameters and evolutionary statuses of six solar type detached eclipsing binaries whose masses are in the range of 0.97-1.43 M⊙. EK Cep and FL Lyr belong to the zero age main sequence.

Implications for compact stars of a soft nuclear equation of state from heavy-ion data [PDF]

, 2012
We study the implications on compact star properties of a soft nuclear equation of state determined from kaon production at subthreshold energies in heavy-ion collisions.

From synthetic SEDs to stellar origins: A deep learning model for physical parameter retrieval in hot subdwarf stars

Astronomy & Astrophysics
Aims. The formation mechanisms of spectrally diverse hot subdwarfs remain unclear. While existing mass distribution analyses suggest additional channels beyond helium white dwarf (He-WD) mergers contribute to He-rich subdwarf formation, these conclusions

The State Complexity of Star-Complement-Star [PDF]

, 2012
We resolve an open question by determining matching (asymptotic) upper and lower bounds on the state complexity of the operation that sends a language L to (c(L*))*, where c() denotes complement.

Radial-velocity measurements of subdwarf B stars [PDF]

, 2011
Subdwarf B (sdB) stars are hot, subluminous stars which are thought to be core-helium burning with thin hydrogen envelopes. The mechanism by which these stars lose their envelopes has been controversial, but it has been argued that binary star ...

Rainbow’s stars [PDF]

The European Physical Journal C, 2017
In recent years, a growing interest on the equilibrium of compact astrophysical objects like white dwarf and neutron stars has been manifested. In particular, various modifications due to Planck scale energy effects have been considered. In this paper we analyze the modification induced by Gravity's Rainbow on the equilibrium configurations described ...
