Gravitational lens effect of a holonomy corrected Schwarzschild black hole

ELB Junior, FSN Lobo, ME Rodrigues, HA Vieira - Physical Review D, 2024 - APS
In this paper we study the gravitational lensing effect for the Schwarzschild solution with
holonomy corrections. We use two types of approximation methods to calculate the …

Gravitational lensing of a Schwarzschild-like black hole in Kalb-Ramond gravity

ELB Junior, JTSS Junior, FSN Lobo, ME Rodrigues… - Physical Review D, 2024 - APS
In this paper, we investigate the gravitational lensing effect for the Schwarzschild-like black
hole space-time in the background of a Kalb-Ramond (KR) field proposed by Yang et …

Microlensing discovery of a tight, low-mass-ratio planetary-mass object around an old field brown dwarf

C Han, YK Jung, A Udalski, T Sumi… - The Astrophysical …, 2013 - iopscience.iop.org
Observations of accretion disks around young brown dwarfs (BDs) have led to the
speculation that they may form planetary systems similar to normal stars. While there have …

OGLE-2015-BLG-1482l: The first isolated low-mass microlens in the galactic bulge

SJ Chung, W Zhu, A Udalski, CU Lee… - The Astrophysical …, 2017 - iopscience.iop.org
We analyze the single microlensing event OGLE-2015-BLG-1482 simultaneously observed

Context. Brown dwarfs are transition objects between stars and planets that are still poorly
understood, for which several competing mechanisms have been proposed to describe their …

MOA-2007-BLG-197: Exploring the brown dwarf desert

C Ranc, A Cassan, MD Albrow, D Kubas… - Astronomy & …, 2015 - aanda.org
We present the analysis of MOA-2007-BLG-197Lb, the first brown dwarf companion to a Sun-
like star detected through gravitational microlensing. The event was alerted and followed-up …
