What could successive double dips in the light-curve mean?
I was going through some analysis of the TESS light-curve data and I stumbled upon an interesting example (see below figures, where the blue line is simply a moving average), where the light-curve ...

How does the size of a naked black hole effect its photon sphere?
What effect does the size of a black hole have on the size or density of the photon sphere and it's proximity to the horizon?
For example: A person is in space looking at 2 black holes, one of them ...

Finding the uncertainty in period for String-Length Minimization calculation
I wrote a Python script that calculates the period of an unevenly sampled data set using the String-Length Minimization method.
You can read about that method here: A period-finding method for sparse ...

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 ...

Depth of primary and secondary minimum in a light curve
How can I explain approximately the same depth of primary and secondary minimum in light curve?
I observe star HD 36486. I tried filters MOST and BRITE.
Is it related with photometric filter? When ...
