Abstract

Secara tradisional, lubang hitam dipandang sebagai objek yang hanya menyerap materi dan radiasi tanpa memancarkan apapun. Namun, perkembangan teori fisika modern mengungkapkan bahwa lubang hitam memiliki sifat termodinamika, salah satunya adalah kemampuannya untuk memancarkan radiasi Hawking, yang memberikan definisi temperatur pada objek ini. Penelitian ini membahas karakteristik temperatur Hawking pada lubang hitam Reissner-Nordström-Anti de Sitter (RNAdS), yang dipengaruhi oleh massa, muatan listrik, serta konstanta kosmologis yang bernilai negatif. Dengan menggunakan pendekatan relativitas umum dan teori medan gravitasi, diperoleh metrik lubang hitam Schwarzschild, Reissner-Nordström (RN), Schwarzschild-Anti de Sitter (SAdS) dan RNAdS dengan mempertimbangkan keberadaan konstanta kosmologis. Temperatur Hawking dihitung melalui evaluasi gravitasi permukaan di sekitar horizon peristiwa. Hasil analisis menunjukkan bahwa konstanta kosmologis berperan dalam meningkatkan temperatur Hawking pada lubang hitam SAdS. Sebaliknya, pada lubang hitam RNAdS, keberadaan muatan listrik mengakibatkan penurunan temperatur Hawking, meskipun konstanta kosmologis masih memberikan kontribusi positif terhadap nilai suhu tersebut. Ketika dibandingkan dengan lubang hitam Schwarzschild, terlihat bahwa baik muatan maupun konstanta kosmologis secara signifikan memengaruhi perilaku termodinamika lubang hitam. Efek gabungan ini bergantung pada parameter-parameter fisik lubang hitam, seperti ukuran dan massa. Secara keseluruhan, penelitian ini memperlihatkan bahwa interaksi antara massa, muatan, dan konstanta kosmologis menghasilkan dinamika termodinamika yang kompleks, yang berpotensi memberikan kontribusi penting dalam kajian gravitasi kuantum dan kosmologi teoretis.

Traditionally, black holes have been regarded as objects that only absorb matter and radiation without emitting anything. However, developments in modern physics reveal that black holes possess thermodynamic properties—one of which is their ability to emit Hawking radiation, thereby endowing them with a defined temperature. This study examines the Hawking temperature characteristics of Reissner–Nordström–Anti de Sitter (RNAdS) black holes, which are influenced by mass, electric charge, and a negative cosmological constant. By employing general relativity and gravitational field theory, we derive the metrics for Schwarzschild, Reissner–Nordström (RN), Schwarzschild–Anti de Sitter (SAdS), and RNAdS black holes, taking into account the cosmological constant. The Hawking temperature is calculated via the surface gravity at the event horizon. Our analysis shows that the cosmological constant increases the Hawking temperature of SAdS black holes. In contrast, for RNAdS black holes, the presence of electric charge lowers the Hawking temperature, although the cosmological constant still contributes positively to the temperature value. Compared to Schwarzschild black holes, both the electric charge and the cosmological constant significantly influence black hole thermodynamics. This combined effect depends on the black hole’s physical parameters, such as size and mass. Overall, this research demonstrates that the interplay between mass, charge, and the cosmological constant produces complex thermodynamic dynamics, which could offer important insights for quantum gravity and theoretical cosmology.
