Paper Roadmap

[18ganesha]

• [ ] create a bilbiography of literature with articles that relate heavily to the HPF spectra research we are doing
• [ ] read papers about the different types of stellar activity (flares, rotational variability, etc.) and see how they change spectra
• [ ] make an ordered list of effects that can mimic a helium exosphere

Here is a useful reference for the effect of stellar activity on the Helium 10830 line spectrum: https://ui.adsabs.harvard.edu/abs/2018AJ....156..189C/abstract

[18ganesha]

• [ ] how to cite websites that do not have an author (ex: HPF/HET website)

[gully]

Usually the information on the website should also exist in a publication somewhere, and may require some searching among instrumentation papers. If not, the AAS Journals Policy provides instructrions for how to cite websites.

[18ganesha]

• [ ] should I make a table with all the observation dates and times and if they are in transit vs out of transit? we can put it in the appendix

[jessicaluna]

I have a spreadsheet with this info, I'll slack you the link

[18ganesha]

• [ ] check which bands of HPF were used
• [ ] how to decript the header abbreviations; what website should I use?

[18ganesha]

• [ ] change TESS/HPF overplot from Calcium triplet to He

[18ganesha]

• [ ] should we add this table for HAT-P-67b observations with just the exposure time, date, and time of observation?

[18ganesha]

• [ ] Should we add a part where we talk about using the Gaussian fit versus the Lorentzian like in the V1298 Tau paper: "We therefore opted to use the simpler Gaussian fit in our final analysis. We restricted the fit to water lines, and allowed for the time-varying shape of these telluric features by fitting each spectrum independently."
• [ ] Should we describe the HPF Point Spread Function?

[18ganesha]

• [ ] because HAT-P-67 is a sub-giant older star, do we still characterize it as highly active? The Cauley article says: "He I 10830 Å is not strongly affected and absorption signatures are likely diluted, rather than enhanced, by stellar activity."

Here is a useful guide for best practices in publishing for astronomy journals: https://ui.adsabs.harvard.edu/abs/2021arXiv210601477C/abstract

The Appendix has a checklist that may be relevant when we go to revise the paper before sending around to co-authors. That's not for a while, so we can simply book-mark this paper until then.

[18ganesha]

• [ ] "A detection of the Doppler tomographic signal, at a depth and width that are in agreement with the photometric transit, eliminates eclipsing binary blend scenarios that may mimic transiting planet signals"; should we add a section on this to show that the signal we get is indeed from the planet and not something mimicing the planet?

[18ganesha]

• [ ] how do I analyze the detection of a Helium signature when the planet is in transit with the host star? What is the range in the flux that I should see changes? How can I tell that it is a change when overplotted with the TESS data?
