With the advent of new surveys, many more SN impostors and peculiar SNe are being found. These discoveries are challenging our current understanding of massive star evolution. Some of the questions we intend to address at the workshop are:
- What is the relationship between massive stars, LBVs and SN impostors?
- What can current observations tell researchers about massive star evolution and instabilities?
- Are Type IIn SNe related to classical LBVs or do they arise from another mechanism?
- Do LBVs originate from the most massive stars?
- Is binarity required for a star to go through the LBV stage?
- How important is inflation for massive star outbursts?
- How do massive stars influence enrichment leading to molecule and dust formation?
Our tentative schedule, intended to maximize discussion at each stage, will devote the first three to four days to massive stars, LBVs and SN impostors in general. The last one to two days will focus more on Eta Carinae, one of the most enigmatic objects in our local group of galaxies and one of the most massive and luminous stars in our galaxy that is conveniently in the LBV stage. Despite extensive investigations we still have many outstanding questions:
- Which star underwent the outburst? What caused the outburst? How much material was ejected?
- What is the enriched ejection telling us about molecules and dust formation?
- Were there only the 1840s and 1890s events, or were there previous massive ejections in addition to the pre-LBV winds?
- What is the evolutionary stage of the secondary star?
The workshop will examine how this massive binary fits into our understanding of these questions and discuss the studies, both theoretical and observational, that are needed as the 2020 periastron event approaches. We will also address what other massive stars, LBVs and SN impostors can and should be studied to provide new insights into massive star evolution.

To and from Pittsburgh International Airport (PIT)
- 28X Airport Flyer: Bus stop at Door 6 in the baggage claim area. Runs every 30 minutes and takes about 1 hour from the airport to Oakland (where the University and the hotel locate). Costs $2.75 (with exact change) or $2.50 with a ConnectCard (available at the airport, near the exit closest to the bus stop).
- Supershuttle: Shared van. Costs about $35 for a single passenger.
- Taxi: Takes 35+ minutes, costs about $55. Options include: Yellow Cab (412-321-8100) and zTrip (412-777-7777).
- Lyft and Uber: Takes 35+ minutes, costs about $35.
- Rental car: there are multiple rental car companies at the airport. Counters are located in the baggage claim area.
Port Authority buses are your best option to travel within Pittsburgh. Fare is $2.75 per trip and must be paid with the exact change. If you are planning on using the bus system throughout the week you can purchase a ConnectCard, which can be loaded with a weekly or 10-trip pass or just cash and can be used for on all Port Authority transports. Lyft and Uber are also convenient options in Pittsburgh.
