Hello Rongrong,

Thank you for sharing your nice presentation slides on heavy-flavor.
Overall your slides look nice and capture all physics measurements of 
STAR.

Here are my additions comments for your consideration.

Slide5:
- "Charm quark gain v2 at T close to Tc" -> what is "Tc" here ? And What 
is the value of Tc? Why it is important?

Slide7:
- "About a factor of 2 suppression…" -> Not clear, with respect to what

Slide9:
- Do you need to refer "QM2023" for this D^0+jet results? Same for next 
slide

SLide13:
- Better to motivate this result with QGP effect can smear D^0-D^0bar 
correlation. But uncertainty limits to pin down

Slide14:
- "Coalescence is important" -> Do we need to mention also "at low pT"?

After Slide16, It would be good to summarize the key physics that we 
observed from open heavy flavor measurements at STAR. Otherwise people 
may be lost.

Slide18:
-"Hint of rising trend toward low energy" -> Is that correct to comment 
within these uncertainties?
_ You could hint to the "primodial" and "Regeneration" effects at high 
and low energies.

Slide19:
-Could you comment on QGP thermal temp based on sequential suppression 
of quarkonia? That is important take away from these results at RHIC.

SLide20-22:
Physics motivation is missed here. Better to say a few words.
Slide21-23:  better to motivate with other pesudoscalar meson results 
from FCV.

After Slide23: You could summarize the key physics learnt from QGP point 
of view.
And then you can go to UPC J/psi results discussion to study other 
Physics not related to QGP.
