Astronomy Colloquium for 2023-04-12

Series: Astronomy Colloquium
Date: Wednesday 12-Apr-2023
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Lily Zhao (Flatiron Institute)
Title: Advancing Radial Velocity Precision Using Data Driven Approaches

Extreme precision radial velocity (EPRV) measurements will reveal low-mass planet compositions, more complete system architectures, better inform planet formation scenarios, and allow for interpretable atmospheric spectroscopy. Achieving this level of precision requires innovation at all levels, from the hardware through to the extracted pectra and the final derived RV measurements. I will give an overview f recent advances in the field that make use of the data itself to reveal ariations and construct data-appropriate models for correcting them. I will conclude by showing examples of the types of work these advancements have made possible.

In-person colloquia are usually preceded by espresso and ice cream at 1:45 pm outside room PSC 1150 and are followed by an informal reception at 5:15 pm in that room. Anyone interested in talking with the speaker, or being added to the colloquium announcement email list, should contact the colloquium organizer Dr. Leslie Sage. Lunch will normally be reserved for the speaker to talk to graduate students. Anyone asking a question during a talk is asked to raise their hand and be acknowledged before speaking. Contact Dr. Leslie Sage for details.
