Resource suggestions?
If I want to research binary stars (to find out about their properties from their light curves) and I need to know how to interpret light curves for the same, what would be a good resource to refer to?...

Using data from the Fine Guidance System (HST)
Has anyone been able to successfully use data from the Hubble Space Telescope's fine guidance system in order to create light curves?
I found a bunch of older papers that reference this instrument, ...

Why does Mars have a jagged light curve?
Caption:
The following chart is the predicted light curve (visual magnitude as a function of time) of Mars, according to the most recent ephemeris data. Magnitude data is sampled with a 2 days ...

Light curves for Chandra
I am working with Chandra data. I only have the corrected PI files for the sources. Is there a way to plot the light curve from this PI file. I wanted to extract the color magnitude ultimately.

Looking for feedback for my python GUI: visualise exoplanet transit and simulate atmospheric temperature
This isn't necessarily an astronomy question (although there may be plenty of astronomy errors in my GUI), and I apologise in advance if this kind of thing is not allowed here and the question is to ...

On the "periodic" lightcurves of Active Galactic Nuclei
So apparently they are all lightcurves of (likely candidates) Active Galactic Nuclei and in some way or the other they all appear to be periodic:
I'd like to know the reason for this and the ...

Why did it take so long for SN1987A to reach peak brightness?
The light from SN1987A first reached us on February 23, 1987, and its brightness peaked in mid May, almost 3 months later.
However, every source that I can find states that it normally only takes a ...

What determines how accurate a particular method is at finding the period between Lomb-Scargle and String Length Minimization?
I've been using the Lomb-Scargle and String Length Minimization methods to find the periods of various astronomical objects with unevenly spaced data. I wanted to see if I could find any patterns ...

Differentiating supernova types with light curves
as an introductory activity for my work on transients, I am studying the light curves of different supernovae. It appears that Type-I supernovae have a more pronounced maximum than Type-II supernovae. ...

Has the new type II supernova SN 2023ixf's subtype been determined yet, and is a tentative light curve possible? Is it still getting brighter?
Wikipedia's article on SN 2023ixf begins:
SN 2023ixf is a type II (core collapse) supernova located in the Pinwheel Galaxy (M101). It was first observed on May 19, 2023 by Koichi Itagaki and ...

Which value of the apparent magnitude do I use from a Supernova light curve
I am trying to get the distance modulus from a light curve of a supernova and obviously the apparent magnitude changes with time. Not only that but there are so many filters with different mags.
So my ...

How to obtain luminosity distance from a light curve
I have some light curve data of a SN Ia from which I want to find the luminosity distance $D_L$.
How can I do it mathematically?
I'll then try to implement the answer using Python.
