Summer students from Green Bank and Charlottesville met at a get-together with mentors and lecturers in Charlottesville. Many of the students in the NRAO-Green Bank program will visit Charlottesville for a tour of the Central Development Laboratory , and of the University of Virginia's facility for the fabrication of the Semiconductor-Insulator-Semiconductor detectors used in millimeter wave receivers, the Semiconductor Device Laboratory.
Water is the dominant consitituent of comets but is unobservable owing to the earth's atmosphere. However, its photodissociation product OH can be observed with the 43m telescope. Unfortunately, not by us--we only established upper limits to the molecular loss rate. Wootten and L. Later in the summer, the Charlottesville students visited Green Bank to use the NRAO telescopes located there, to meet members of the Green Bank staff, and to attend the annual picnic.
The students wrote a Target of Opportunity proposal to measure OH in comets which was awarded time. The students gave a series of 15 minute talks on their projects during a lunch symposium in Charlottesville before they begin leaving for the summer.
They produced short reports describing their summer research. One highlight will be the placing of the backup structure onto the Green Bank telescope GBT , the world's largest steerable telescope.
It is an offset parabaloid, m across the longest axis, incorporating 16 million lbs of steel in the moving structure. The surface is more than half complete on the structure; during the rest of the year it will be completed. We went go to Green Bank for observations, and watched the process. During the course of the summer, the students conducted several short observing sessions in Green Bank on the 43m telescope, and toured the Green Bank Telescope, in a final phase of construction this summer.
The 40 ft telescope there is a student telescope, open for any project which students would like to carry out on it though its instrumentation is limited. If there is interest, we may carry out, probably remotely, a project on the VLA or 12m telescope in Tucson. We're very excited about the Millimeter Array , which was selected as the top priority for a new astronomical instrument in the 90s back at the beginning of the decade by the Astronomy Survey Committee.
Funding has been approved and should begin in June Device Fabrication Facility U. This proposal undertakes an investigation of deuterated molecules as an alternative method of examining such objects. These results indicate that deuterated species can underscore the kinematic and chemical evolution of low--mass protostars forming Solar--analogs. This proposal's goal encompasses understanding the dynamics of star--forming material, and the coeval physio--chemical effects denoted in spectra of deuterated molecules.
This will be accomplished with single--dish and interferometric observations, and archived infrared and X--ray data in order to address protostellar evolution models.
This may eventually aid in understanding the evolution of the Solar Nebula. Tidal just gravitational forces strip stars and gas out of a galaxy into elegant tidal features while other material is compressed causing copious star formatio n.
The fact that all these effects are the result of simple gravity is astonishing. See our listing of NRAO graduate interns and their research topics since for examples of past graduate internship projects. Students interested in pursuing graduate internships should first contact an NRAO scientist or engineer to discuss possible projects. Graduate Internship appointments are considered on a rolling basis, and there is no formal application.
Staff Policies Diversity. Skip to navigation my. You will also write a 4 page minimum report outlining your summer research, and present this to your advisor and local Summer Student coordinator by the end of August. The NRAO may have a small amount of funds to help students attend the winter meeting of the American Astronomical Society in the January following their appointment, for the purpose of presenting a poster or talk about their summer research project.
If the NRAO advisor advocates that it would be worthwhile for the student to attend this meeting, then the student should prepare a proposal. The student coordinator will provide more information on this toward the end of your summer term. To be eligible for NRAO support to attend the AAS, the student must have submitted a written report outlining their summer research to their local Summer Student coordinator by the end of September.
Students will not be provided with health insurance. It is likely that you will be covered under your school or family's plan during the summer. Students should check this and carry any necessary medical insurance documents.
After you accept a summer student appointment with NRAO, you will be sent an acceptance package. This package will contain the following information:. Please fill out and sign the appropriate forms, and return to us in the enclosed self-addressed stamped envelope. Issuance of stipend checks is contingent upon prompt return of the forms. Soon after, you should receive a mailing from your assigned site, containing information on local housing and reporting information.
The following links provide additional information specific to the individual NRAO sites to which students may be assigned. This includes local history, weather, travel, directions including maps to the NRAO sites, housing, and contact information.
The program runs from weeks over the summer, from late May to mid-August. At the end of the summer, participants present their research results as a short talk and submit a written report.
Often, these projects result in publications in scientific journals. Financial support is often available for students to present their summer research at a meeting of the American Astronomical Society , generally at the winter meeting following their appointment.
Besides their research, students take part in other activities, including a number of social events, excursions, and summer schools.
