This article follows a simpler approach (Siddiqui et al. 2011, Chin. Phys. Lett. 28, 050401) using foliation’s concept with virtual displacement of hyper-surfaces near the event horizon to derive the first law of black hole thermodynamics for the Kerr black hole spacetime.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
