Kelt-19Ab Co-Discovery

Kelt-19Ab Co-Discovery

This is my 16th exoplanet co-discovery using the transit method, I have a dozen more from RV collaborations.

Here is the link for the paper in arxiv https://arxiv.org/pdf/1709.07010.pdf

Panoramic of the several LC's used to frame this one down extracted from the discovery paper.

On the 5th of December 2016 I chose this candidate has a target for my observing plan.

The equipment used was an SCT 0.3m FL1700mm on a Losmandy G11, the camera a SBIG ST-10XME with a KAF3200M and a CFW10 filter wheel.

The filter used was a photometric Ic-band from Custom Scientific and 180s exposures. The observation of the full transit event lasted for 6h34 in a total of 128 images.

Below is the resulting plot of the observation data.

The transit signature is well defined, the transit duration is 0.1831 days (~4h39)

Looking around I also found a couple of nice variables.

This plot I call it the wild beast in the sky.

 

Under construction, return later
