Peranso

[Mr Roger Dymock]

Good afternoon,

Has anyone any experience they could share of using Peranso to process exoplanet phase curves or any other aspects of exoplanet analysis.

I’m a frayed knot.

There’s a nasty echo around here. 😉

(Sorry if the levity offends anyone. I’m feeling slightly hyper at the moment because I’ve just shut down the observatory after an unusually productive night.)

Roger,

Can you expand a bit about your phrase, “to process exoplanet phase curves”?

The software aims to identify periodicities in data, so it needs lots of data spanning many cycles. It might be helpful if you take everyone’s data going back several years and search for the periodicity that way.

To be a little more serious this time. I may be able to help to some extent, though not with Peranso (my “a frayed knot” comment) because I picked up a very low amplitude EA variable in my analysis of MAXI J1870+070 data. On that occasion I was lucky because an entire primary eclipse occurred in a single night’s data. Subsequent analysis of a few weeks data, not with Peranso, dug out the secondary minimum. The depths are about 25 and 10mmag respectively, well within the range of an exoplanetary transit. Until the secondary showed up I did wonder whether an exoplanet had been found.

All this took place almost five years ago and I will need to refresh my memory before more detail can be given. One of the projects still waiting for another delivery of round tuits is to see what else can be found in this data set and a few others waiting in storage.

Hi Richard,

I am using the SLOOH 0.5m telescope to obtain 5 images per night of TOI-1259A b. After a month or so I will process these with Astoimagej for photometry and then construct a folded phase curve using Peranso. Only just started to learn the latter so might take a while.

Hi Paul,

Sounds quite interesting especially about the secondary eclipse. Please let me know of any developments.
