Astronomy Colloquium for 2018-10-24


Series: Astronomy Colloquium
Date: Wednesday 24-Oct-2018
Time: 16:05-17:00 (4:05-5:00 pm)
Location: ATL 2400
Speaker: Dr. Armin Rest (STScI)
Title: High-cadence Light Curves of Transients from the Kepler Telescope

Despite the expanding set of SNe discovered in recent surveys like PS1, ATLAS, PTF, and ASAS-SN, several fundamental questions remain of the nature of these explosions and their progenitor systems. The early light curves of SNe contain the critical information to understanding the nature of the progenitors and explosion physics: detonation, deflagration, and inwards-moving diffusion waves and much more. However, it has been difficult to obtain early light curve data with sufficient cadence and accuracy from the ground. With K2, and in the future TESS, we are now able to obtain high-cadence early light curves with exquisite photometric accuracy for thermonuclear and core-collapse SNe. I will discuss our growing and diverse sample of transients with high cadence light curves, ranging from SN Ia and IIPs to more exotic events like IIb's, fast transients, and TDEs.


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. Lunch will normally be reserved for the speaker to talk to graduate students.

Colloquium Organizer: Prof. Richard Mushotzky
