Conference/Workshop objectives
Dear SAC members, we would like to invite you to the 4th SAC Scientific Retreat, which will take place from 19-22 October, 2015, in Skagen. Three years after it was founded, SAC has successfully extended to six international nodes, and is taking part in several world wide instrumental projects. In the context of the midterm evaluation, and of the application for the extension of our Centre of Excellence, it is time to review the present state of our collaborations and discuss the strategic plan for the upcoming years. The reflexion will be conducted through scientific talks, splinter sessions and workshops. The format of the meeting will also include a poster session. We ask each member, including the non-scientific staff, to bring a poster: what would you like to share with SAC? This could be scientific results or projects, as well as other topics which fall under SAC's missions, such as working environment, teaching or outreach. We intend to print all posters locally. Thus, we would appreciate if you could send a title by October the 9th, and the full poster (A0 pdf format) by October the 13th at the latest. It is expected that all SAC members, from MSc level onwards, take part in the retreat, and registration is necessary.  In order to fulfill this ambitious programme, the retreat has been extended to three days. Please note that we have arranged for a bus to take us from Aarhus to Skagen (departure from Aarhus University at 13:30 on Monday, and arrival in Aarhus at 22:00 on Thursday). Looking forward to seeing you all in October Rhita-Maria Ouazzani Brigitte Henderson Hans Kjeldsen Joergen Christensen-Dalsgaard

Conference venue Skagen, Denmark
Hotel information A couple  of miles across the peninsula on the wilder west shore, this place in Old Skagen was founded by a local lifeboatman in the early 20th century. The spacious, airy rooms take maximum advantage of the famous light. A private terrace looks out to sea, giving a prime view of the sunset. Ruths Hotel Gl. Skagen DK 9990 Skagen +45 9844 1124 info(at)ruths-hotel.dk "Skagen is Denmark's northernmost town, located 41 kilometres (25 mi) north of Frederikshavn, 108 kilometres (67 mi) northeast of Aalborg, and 226 kilometres (140 mi) northeast of Aarhus by road.
It takes its name from the peninsula which projects into the waters between the North Sea and the straits of Denmark. The oldest areas lie along the south coast or Sønderstrand. Gammel Skagen (Old Skagen), also known as Højen, is located next to Nordstrand on the western side. Vesterby and Østerby are notable for their little fishermen's cottages and narrow streets.

Danish national road 40 to Frederikshavn passes through Skagen.
Travel information We have booked a bus to take us to Ruths Hotel after lunch on 19 October. The bus leaves at 1pm from the parking lot between the Department of Physics and Astronomy and the Chemistry Department (see map) If you arrive to Aarhus prior to 19 October, you will find the ways of reaching Aarhus below:

Flights

Copenhagen airport is the largest airport in Denmark, but there are also two smaller airports in the area, Aarhus (Tirstrup) and Billund.

Aarhus Airport (AAR)

  • Aarhus Airport (Tirstrup) is fairly small and has frequent arrivals from Copenhagen (approx. 7 flights per day), London (Stansted), Oslo, Stockholm, Gothenburg and a few other destinations depending on the season. The London flights are from Stansted and are operated by Ryanair, who also operate a few other seasonal routes. Flights have to be booked directly with Ryanair online. Most other flights into Aarhus Airport are operated by SAS (from Copenhagen) and British Airways and can be booked either online or through a travel agent. For a full list of destinations from to/from this airport see the Aarhus Airport website.
  • There is a 45 minute bus ride to the centre of Aarhus which costs 100 DKK, and stops both close to the University (see the map directly below) and in the centre of the city (see map at the bottom of the page).  Click here for the timetable for this bus service (lufthavn=airport). If the English version returns no results for the timetable then use the Danish version to find bus times between Aarhus airport and the city centre.
  • Further information regarding Aarhus airport can be found at http://www.aar.dk which gives details (in English and Danish) of flights, the bus service and car rental.

Billund Airport (BLL)

  • Billund Airport is much larger than Aarhus Airport and has arrivals from many European destinations.
  • The bus ride into the centre of Aarhus takes ~1hr and 40 minutes and costs ~160DKK. The bus stops in the centre of the city, at the coach station (Rutebilestation). The location of the stop is shown on the map at the bottom of this page. Information about Billund Airport can be found at http://www.bll.dk (currently in Danish only, but has limited English information as well). Click here to view the bus timetable between Billund airport and Aarhus.

Copenhagen Airport (CPH)

Copenhagen Airport is the largest airport in Denmark, with hundreds of flights a day from around the world. To reach Aarhus from this airport you need to either take a connecting flight into Aarhus airport or take a train.
  • By air from Copenhagen to Aarhus: The flight takes only 20 minutes and if your flight into Copenhagen is with one of the Star Alliance airlines you can usually buy the connecting flight to Aarhus included in the ticket.
    You will then need to take the airport bus into the centre of Aarhus (see above).
  • By train from Copenhagen to Aarhus: There are direct trains from the airport to the centre of Aarhus which take about 3 hrs 30 mins. (There are other trains which require a change at Copenhagen main railway station). The price of a one way ticket is 358 DKK and to reserve a seat is 30 DKK (recommended for journeys during peak hours in the morning and evening). For more information see the train information below.

Trains

Aarhus main train station

  • The main train station in Aarhus is in the centre of the city. There is a direct service from Copenhagen to Aarhus which takes about 3 hours, with at least one train an hour. Click here for the DSB journey planner to find more about train services within Denmark.
  • There are also some train connections to other European countries, including a daily, direct train from Berlin, which takes about 6 hrs 30 mins.

Abstract:
There is no one observable that is sensitive to age and age alone. However, some combinations of parameters such as large frequency separation and small frequency separation are more sensitive to age. The age can be better constrained by comparing these observables with parameters extracted from stellar models. Extracting ages from stellar models is an optimization problem that seeks the initial stellar conditions and amount of time elapsed that gives the best fit to a measured set of observables.
