Gravitational microlensing as a test of stellar model atmospheres [PDF]
, 2002 We present calculations illustrating the potential of gravitational microlensing to discriminate between classical models of stellar surface brightness profiles and the recently computed ``Next Generation'' models of Hauschildt et al.

Blending in Gravitational Microlensing Experiments: Source Confusion And Related Systematics [PDF]
, 2007 Gravitational microlensing surveys target very dense stellar fields in the local group. As a consequence the microlensed source stars are often blended with nearby unresolved stars.

Detecting Multiplanetary Systems with Gravitational Microlensing and the Roman Space Telescope
The Astronomical Journal, 2023 It is plausible that most of the Stars in the Milky Way Galaxy, like the Sun, consist of planetary systems, instead of a single planet. Out of the estimately discovered 3980 planet-hosting stars, about 860 of them are known to be multiplanetary systems ...

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 Nonsingular Ayon‐Beato‐Garcia (ABG) spherically symmetric static black hole (BH) with charge to mass ratio q = g/2m is metric solution of Born Infeld nonlinear Maxwell‐Einstein theory. Central region of the BH behaves as (anti‐)de Sitter for (|q | > 1) | q | < 1.

Bose‐Einstein Condensate Dark Matter Halos Confronted with Galactic Rotation Curves
Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017 We present a comparative confrontation of both the Bose‐Einstein Condensate (BEC) and the Navarro‐Frenk‐White (NFW) dark halo models with galactic rotation curves. We employ 6 High Surface Brightness (HSB), 6 Low Surface Brightness (LSB), and 7 dwarf galaxies with rotation curves falling into two classes.

The Microlensing Planet Finder: Completing the Census of Extrasolar Planets in the Milky Way
, 2004 The Microlensing Planet Finder (MPF) is a proposed Discovery mission that will complete the first census of extrasolar planets with sensitivity to planets like those in our own solar system.

Higher order corrections in gravitational microlensing [PDF]
Physics Letters A, 1999 We show that, in cosmological microlensing, corrections of order $v/c \sim / $, to the deflection angle of light beams from a distant source are not negligible and that all microlensing quantities should be corrected up to this order independently of the cosmological model used.

Microarcsecond instability of the celestial reference frame [PDF]
, 1998 The fluctuation of the angular positions of reference extragalactic radio and optical sources under the influence of the irregular gravitational field of visible Galactic stars is considered.

Advances in Astronomy, Volume 2014, Issue 1, 2014., 2014 The perturbation caused by planet‐moon binarity on the time‐of‐arrival (TOA) signal of a pulsar with an orbiting planet is derived for the case of the orbit of the planet‐moon system inclined of an angle α with respect to the plane of the orbit of the planet‐moon barycenter around the pulsar.
