Department of Astronomy 2022-2023 Colloquium Series Presents:
Dr. Gabriele Cugno & Dr. Taylor Tobin Post Doc Colloquium II
Gabriele’s Title: Observing planet formation in multiple wavelengths
In the past two and a half decades almost five thousands extrasolar planets have been detected, and many more will be discovered in the next years. From these observations, it immediately appears clear that planetary systems are extremely diverse in terms of architecture, orbital parameters and chemical composition. To explain the observed properties, we must understand how planets form and evolve with time. Interestingly, different components of a forming planet emit at different wavelengths, and we can observe forming gas giants in different filters and bands to study individual processes. In this talk, I will explore the potential of multi-wavelength observations and discuss latest results and future prospects to unveil how planetary systems form.
Taylor’s Title: Pictures of Exoplanets around Accelerating Stars:
A Near-Infrared Direct Imaging Survey with SCExAO/CHARIS
Directly imaged exoplanets are uniquely positioned to provide observational insight into planet formation models. In addition to providing astrometric tracking and spectral measurements for each detected planet, direct imaging at near-infrared (NIR) wavelengths targets young exoplanets, still cooling from their formation. However, exoplanets that are detectable with current NIR imagers are rare. To amass a sufficient sample of imageable exoplanets for more robust studies of their atmospheric chemistry, formation, and evolution, targeted surveys are needed. In this talk, I will discuss progress from the ongoing NIR direct imaging survey with SCExAO/CHARIS targeting stellar systems displaying astrometric evidence of possible companions, as well as CHARIS’s new automated data processing backend, ADEPTS.
