Oggetto: Astronomy Seminar Friday 8th of May: 10:30 zoom: Leonardo Tartaglia


Dear all,

On Friday the 8th of May we have the next Astronomy seminar remotely via zoom at 10:30.

Our speaker is Leonardo Tartaglia from the Astronomi Department (SU)

Title: Interacting supernovae and their progenitors from long-term monitoring

Abstract: While modern surveys are able to discover and classify new optical transients within
one day or less from their explosions, the proper characterization of their progenitor
stars is still a partially unsolved astrophysical issue.
The most common interacting supernovae are believed to arise from the core-collapse of
massive stars ejecting fractions of their envelopes during the last stages of their lives.
Direct evidences of luminous blue variables as progenitors of these transients is enclosed
in deep archival images, while several indirect evidences point to less massive stars as
candidate progenitors of at least a fraction of these transients.
Indirect methods can help us to determine physical properties of progenitors and their
surroundings, and require high-quality data, and good multi-wavelength monitoring of
interacting transients up to very late times after explosion.
During this colloquium, we will see how long-term photometric and spectroscopic follow-up
campaigns, combined with early discoveries and multi-wavelength observations, can help
us in characterizing this relatively rare and still poorly understood class of optical transients.

We will have the colloquium using zoom. You will find the invitation at the end of this email.

Some guidelines:

1) Join the session with your microphone muted.

2) When you have a question, press the “raise hand button” and wait till you are asked to ask your question.

3) The session will be online from 10:20, please join at least a few minutes early as we would like to start 10:30 sharp.

We hope to see all of you there!

Arjan & Cristina
