Summary

The K2 Mission and Boston University will host a Dwarf Stars and Clusters Workshop on Jan 16-18, 2018, at BU in Boston, Massachusetts.

Since its launch in 2009, the Kepler telescope has been providing high precision photometric time series on half a million targets, from exoplanet hosts to active dwarf stars. With its focus on the ecliptic plane, the K2 Mission has further expanded science opportunities, especially in the area of stellar clusters and magnetic activity. By the end of 2017, K2 will have observed more than 15 open clusters and associations, some on more than one occasion. The resulting data have enabled ground-breaking research on a number of topics, including gyrochronology, stellar rotation and activity, planet occurrence rates, young stellar objects, and eclipsing binary systems. Astronomers working in these areas are warmly invited to gather for discussion at BU this coming January.

The motivations for this workshop include:

Summarizing the science done to date with K2 in the area of cool stars, star formation regions, and open clusters.
Forging new collaborations for future science with K2.
Exploring synergies with other space missions (especially TESS), wavelength regions, and science areas.

Agenda

This will be a small workshop with time for most participants to give a short overview of their research during the first two days. Talks are 10 minutes each, plus 5 minutes for questions. (There will not be any posters.) We have reserved the final morning for "unconference" activities, including data how-to's and high-level science product creation overviews. We will also encourage participants to spend time comparing technical approaches to K2 data, including photometry.

Venue

The workshop will take place on the Boston University campus, primarily at the College of Arts and Sciences.

The nearest airport is the Boston Logan International Airport. We recommend using the MBTA system, which provides public transportation from the airport.

For those that wish to drive to campus, there should be parking available at the Granby Lot, 665 Commonwealth Ave or the Kenmore Lot, 549 Commonwealth Ave., at a cost of $17 per day. If these are full, there are other parking options available. Attendants at the Granby and Kenmore Lots can offer directions.

For the first two days, the workshop will be held at the College of Arts and Sciences (CAS; home of the Institute for Astrophysical Research). Upon reaching the College of Arts and Sciences (home of the Institute for Astrophysical Research), proceed to the northwest end of the building near the Marsh Chapel. Talks will be in CAS 211, and coffee breaks in CAS 500 and 502. Look for signs directing you to the meeting.

For lunch, we suggest the George Sherman Union, but you can also take a look at our list of other nearby options.

On the third day, the Unconference will take place in the Terrace Lounge of the George Sherman Union (GSU). GSU is also our suggested lunch site. It is located at 775 Commonwealth Ave. Right click on the above map and select 'view image' to see a larger version.

Accommodation

There is no on-site accommodation available for this meeting, but we can recommend the following nearby hotels:

The Hyatt Regency Cambridge is just across the river and walkable (at most 15 minutes) and has rooms for approximately $150-200/night + tax.
Hotel Buckminster is on the BU side of the river, in Kenmore Square. Prices range from $110-150/night + tax.
Hotel Commonwealth is also in Kenmore Square, but a bit more pricey.
Students on a budget may want to check out the hostel in central Boston.
For other options, check out hotels on the B or C Green Lines, such as the Holiday Inn Boston-Brookline (about 20 minutes' ride).
