The Applicability of the Astrometric Method in Determining the Physical Parameters of Gravitational Microlenses Cheongho Han Department of Astronomy & Space Science, Chungbuk National University, Chongju, Korea 361-763 cheongho@astro-3.chungbuk.ac.kr Kyongae Chang Department of Physics, Chongju University, Chongju, Korea 360-764 kchang@alpha94 Astrometry is used to look for the periodic wobble that a planet induces in the position of its parent star. The minimum detectable planet mass gets smaller in inverse proportion to the planet's distance from the star. A space-based astrometric instrument had been planned (SIM Lite) that could measure an angle as small as 1 micro-arcsec. Astrometry Method to Detect Exoplanets : Astrometry is the science of precisely measuring the position of the objects in the sky.The gravity of a planet, how As we know, the exoplanets are mostly detected by the methods of radial velocity and transit, up to now only one is found by the astrometric method.

Astrometric method

Other methods at exoplanet astronomers' disposals include detecting gravitational lensing due to a planet (called the microlensing method), searching for the wobble in the star's position on the sky (called the astrometric method), and separating the light of the star from the planet and actually taking images (called the direct imaging method).

In fact, for laboratory often use ampoule sealed method to storage.

Astrometric method

Current technology limits its use to very rare cases. Astrometry is the branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies.The information obtained by astrometric measurements provides information on the kinematics and physical origin of the Solar System and our galaxy, the Milky Way. The general analysis methods can be applied to astrometric observables appropriately defined for both monopupil and diluted‐aperture telescopes, both from the ground and in space. To this end, I describe the techniques in terms of the basic observable and noise models and the estimation process. The astrometric method is the only way to determine the masses of those components which could either be stars or planets except when a pair of objects is seen transiting each other (orbital plane is along our line of sight). Astrometry today and tomorrow ASTROMETRIC METHODS FOR PLANET SEARCHES 1023 2005 PASP, 117:1021–1048 erences therein), but none of them can alone represent the observed distribution in a natural way. Furthermore, in mul-tiple-planet systems, different eccentricity excitation mecha-nisms induce different evolution of the orbital alignment, and In ASTAP solver more or less the same process is followed.

This process will be done for the image and repeated for the stars in the star database. The photo-center of a close double star in which one component has a variable luminosity moves on the sky in the same rhythm as the total luminosity of the system varies in time. This provides an astrometric method to detect the binary nature of the system if more direct methods fail. We propose to call such systems `variability-induced movers', or VIMs. We discuss the required properties of a Noun 1. astrometry - the branch of astronomy that deals with the measurement of the position and motion of celestial bodies astronomy, uranology - the branch of physics that studies celestial bodies and the universe as a whole All-sky photographs, used in meteor astronomy, need a special transformation formulae for converting the plate coordinates to celestial coordinates.

It dates back at least to statements made by William Herschel in the late 18th century. Abstract As we know, the exoplanets are mostly detected by the methods of radial velocity and transit, up to now only one is found by the astrometric method. As the data of the gaia will be soon released, astrometry will gradually become one of the most important methods for detecting exoplanets.
