Detected my first (previously known) Exoplanet!

[Stefannebula]

Last night I detected my first (previously known) exoplanet! I did this by the tried-and-true transit method.

The exoplanet I chose is called WASP-19b, it is located around 880 LY away in the constellation Vela. It is a Jupiter-sized planet with an orbital period (year) of less than 19 earth-hours!

Definitely room for improvement of the data quality, would probably better to have a higher focal length than my current 420mm. Still very happy, didn't know whether it would work at all, I was overjoyed when I plotted the data and saw the dip!

Multi-aperture photometry measurements made in AstroImage J, and model fitting performed on Exoplanet Transit Database online light curve model-fitting tool.

Equipment:
SharpStar HNTF2.8 420mm
ASI183MM-Pro
NEQ6 Pro
Optolong Luminance filter

Exposures:
300*30s (gain: 50),-15C, bin1x1
L filter

Well done !:thumbsup:

Amazing - who would have thought you could be detecting interstellar planets from your backyard?

Congratulations :)

Just wondering, should this image be posted in the "planetary" section, or the one for DSO's? :question: :lol:

This is the coolest thing ever :)
Huge congratulations!!! I'd be so stoked with that. Incredible :)

[Stefannebula]

Thanks a lot everyone! I was genuinely surprised it worked first try!

Granted the data quality could absolutely be improved, but that's something I'll work on the more I do this :)

Just Amazing that amateurs can now do this kind of research . :thumbsup:

Really great stuff

[gaa_ian]

That’s a great achievement 👍 up here, we wold be happy for the clouds (and cyclones) to bugger off

Well done...inspirational!

[rustigsmed]

awesome stuff Stefan! congrats!

[Hemi]

Agree with everyone else: Brilliant Stefan, I will research this and have a go...very inspiring.

Fantastic!

Stefan,


Nice result, even with the noisy data it looks real to me. With regards to the focal length I don't think it would improve things as you are only measuring changes in brightness and that is unlikely to be different with a longer focal length. All these measurements are going to be limited by the atmosphere.

Was wondering how feasible this was for amateurs. Awesome work!! :thumbsup:

[morls]

Wow, that’s very impressive, well done indeed!

[Atko90]

I had no idea this was possible in the amateurs world! Thanks for sharing :)

There are a few Amateur Astronomers doing research on Exoplanet Research. One of the best is an Australian .. TG Tan ...

Just shows what can be done.
