Abstract: There are now thousands of known exoplanets in our galaxy and yet characterizing them remains a technical challenge. Solar system planets and brown dwarfs can serve as benchmarks for exoplanet observations and they provide high signal-to-noise data that we cannot yet access for exoplanets. My research combines instrumentation development with observations of brown dwarfs and solar system planets to advance our ability to interpret exoplanet atmospheres. In this talk, I will present an overview of the NIRSPEC upgrade for Keck Observatory, which made the instrument more sensitive for observing exoplanet and brown dwarf atmospheres. Then, I will present preliminary work using upgraded NIRSPEC to track time-resolved varying spectral features to create 2D surface maps of cold brown dwarfs. Lastly, I will discuss a new instrument that I designed and built for Lick Observatory, the Planet as Exoplanet Analog Spectrograph (PEAS) that observes solar system planets as if they are point-source exoplanets. Zoom guidelines and information As a reminder, please keep yourself muted during the meeting unless you are speaking. If you have an important clarification question, please raise the “blue hand” in the Participant list before asking or you can ask a question in Chat window. For non-urgent questions, please wait until the Q/A time following the presentation. Refreshments will be served outside on the lawn between Kuiper Space Sciences and Flandrau Science Center under the Moon Tree, weather permitting, at 3:20 p.m. You may join the talk from your office, or with your colleagues in Kuiper 308. Questions will be moderated both on zoom and in room 308. Masks are required in the seminar room. Refreshments are not permitted in the seminar room.
