Abstract
\n\nWe present results from the archival analysis of all high resolution spectra of cool stars observed with Chandra/HETG. Thanks to the spectral resolution of HETG, we can study the individual emission lines from these stars and now have hundreds of observations to make a comprehensive study between the Classical T Tauri (CTTS) versus the Main Sequence (MS) stars possible. These emission lines reveal the physical conditions of the outer layers, which are expected to be different between active coronae and accreting young stars. Our preliminary results show that (i) in the R versus G plot, the prototypical CTTS TW Hydrae exhibit smaller density for longer wavelength lines (like Ne and O). (ii) We also perform temperature diagnostics by plotting the soft excess (i.e., H/He lines of Si, Mg, Ne and O) versus their respective line luminosities. We find a positive correlation between these two quantities.
\n\nInterestingly, we also find that irrespective of whether the stars have undergone flaring during the Chandra observation or not, the trend remains the same. (iii) Finally, we report that the CTTS TW Hydrae can be distinguished as separate in the Ne X/ Ne IX versus the O VIII/O VII plot when compared against other MS stars. We discuss our findings in the light of the influence of accretion on these line formations.

In addition, individual and collective contributions from (parallel) Topical Interest Rooms are welcome. If you would like to submit a typical conference proceeding, there are no formal page limits. For guidance we recommend you limit yourself to 4-8 pages for contributed talks and 10-15 pages for invited talks. Those wishing to submit a written conference proceeding are encouraged to format the document using the CS20 LaTeX template (available on https://github.com/CoolStars20/proceedings/releases/latest). All such submissions should be made as PDFs and will be reviewed for content by the SOC and we may suggest edits.
\r\n\r\nSubmission of presentation slides from speakers and full posters are also encouraged. PDF versions of these documents are the preferred format for Zenodo contributions to permit the documents to be previewed in a web browser. For maximum impact, a written contribution may be provided with presentation slides and/or a poster to provide greater context. Contributions will be checked for the proper metadata. Instructions about how to prepare your contribution are available on http://coolstars20.cfa.harvard.edu/contributions.html
