Introducing TTV project in Iota Middle East

Introducing TTV project in Iota Middle East

Planet detection from transit timing variations is a method for determining the existence and properties of a planet from the gravitational perturbations it induces on the orbit of another, transiting planet. In an unperturbed planetary system consisting of a star and a planet, the two bodies revolve around their center of mass in a Keplerian orbit. If in this system the planet transits the star, it will cross the disk of the star at same time during each transit. If because of some external perturbation (e.g., a second planet) the motion of the transiting planet deviates from purely Keplerian, the time of the mid-transit will be different from one orbit to another. This is known as transit timing variation (TTV). (Haghighipour, Nader. "Planet Detection: Transit Timing Variation", 2014)
A group in Iota Middle East is working on this project in collaboration with groups in other countries. We all will be glad if other enthusiastic researchers or groups join us in this exoplanetary project.

Predicting outgassing and instabilityof asteroid TB 145 in passing of the Earth’s orbit

The recent discovery of the asteroid TB 145 (also categorized as comet, Because of its highly eccentric orbit and inclination)[1] is a good opportunity for a precise observation by the observatory and institutes all over the world. From its orbital path[1], it is predicted that it will pass the orbit of the earth from the distance of 1.3 times the lunar distance from the Earth.

The first successful observation lunar Occultation in daylight in the Middle East

observational Aldebaran occultation data planning has done by occultation department of IOTA-ME, Dez Scholars Institute and Adib Astronomical Center of Isfahan, this work has done during the day. This occultation date was on 09/05/2015 at 06:36:54 GMT (11:06:54 local time). The occultation has successfully observed, timed and recorded by Dez Scholars Institute and Adib Astronomical Center of Isfahan. IOTA/ME was the data collector and all of the reports have sent to the global data collector of IOTA, Mr. Gault which he confirmed the Iranians' reports ...
