FRIDAY, JUNE 4, 1937 THE MICHIGAN DAILY Finish 2-Year Spectrum Study Of Small Star Prof. McLaughlin Relates Work Now Being Done With Stellar Photos By SHIRLEY FISHMAN The completion of a two-year study of Nova Herculis ,a temporary star,' by the University Observatory is the I latest addition to the field of stellaI spectra, the study of stars by their spectra, work in which the observa-E Van Devanter Rids Hughes Farewell Play Production Sailing Ship Offers Free Sea Training Jors Nationall A free course in practical experi- e r ence on board one of the world's larg- T est sailing ships, the "Marsala" is be- Michgan' Pl Ping offered this summer to boys and Michigan's Play Production, stu- young men between the ages of 10 tory has specialized for 26 years. Prof. Dean McLaughlin stated in an in- terview recently. The chemical composition of a star, its temperature and rate of speed to or from the earth can be determined' by a study of- the photographs of the star's spectrum, he stated. Various dark lines differing in their intensity and position in the spectrum are ob- tained on the negative, from whichJ one is able to determine the chemical composition of the star's atmosphere, he explained. "For instance the ele- ment hydrogen will produce a dis- tinctive pattern of lines which no oth- er element can duplicate," Professor. McLaughlin added, Machines Measure Motion The rate of speed a star is traveling can be determined by the distance the bands vary from the normal position on the photographic plate and the slight change in the wave length. Six machines at the Observatory can measure these displacement lines to within one fifty-thousandth of an inch and thus a stars motion may bej measured to one half a mile per sec- ond, he said. "Stars hose spectra appear ab- normal are those with which most of the work in the observatory is con- cerned," Professor McLaughlin stat- ed. The spectra of one of these ab- normal classes contains bright lines of hydrogen instead of the usual dark lines on the photographic plate. An- other class, to which the Nova Her- culis belongs, is composed of tem- porary stars which without warning suddenly appear brilliant in the heav- ens and then slowly disappear, he showed. Stars Chaoge In Size" By the 13,500 photographs the ob- servatory has taken it is shown that Gent dramatic group, was elected to membership in the National Theatre Conference recently, it was an- nounced here yesterday. The Conference includes 25 leading1 little theatre and university groups of the country. Recently organized, it elected 11 new members in its meet- ing last week, approval being neces- sary by 12 of the original 14 members. The purpose of the Conference is to aid little theatres in obtaining or- ganization and better selection of plays and materials for production. And to enhance the opportunity for better non-professional dramatic work in the United States. Play Production also has been hon- ored this spring by "Theatre Artsf Monthly," international magazine. This month's issue includes a picture of the Players in their performance of "The Old Maid" which they gave last year. The July issue will have an article by Prof. Valentine B. Windt, director of the group, on "Directing Amateurs." It will also have a picture of last year's offering of "The Pirates of Penzance" and this year's Henry VIII."

Students join the ship in the vi- cinity of New York Harbor and may remain on board from June 1 to Oct. 1 for any period of not less than three weeks. The cadets will follow regular daily ship routine receiving instruc- tion in nautical subjects under the supervision of the Captain Comman- dant of the Academy. This is the eighth year the course has been given to acquaint boys with the possibilities of a career as officer in the U.S. Mer- chant Marine. Instruction, living quarters and medical attention are free. The only expense will be meals. JANITORS TO MEET The Union of University Janitors will hold a meeting to elect perina- bor Hall, Will Canter, former chair- man of the union, announced last dent of the union, announced last night. An important discussion of organization problems will follow Youth Congress Meeting To Be In Milwaukee~v The Fourth American Youth Con- gress will meet July 2-5 this year in Milwaukee, Wis., it was announced recently by that body. This year's program will take the form of a model Congress of the United States. The group will in- clude a Senate, a House of Represen- tatives, joint committees and organi- zational caucuses. Each local youth organization is entitled to one rep- resentative for each fifty members and each national organization to four members in the Senate. Committees will be appointed by the cabinet which will be nominated ind elected at the first and second meetings. Subjects to be covered by ;hese groups include: agriculture, democratic liberties, education, labor, peace, recreation and leisure time. G.M.

It -- ------ ------------ most disappeared while others have grown stronger. A theory advanced is that stars form new atmospheres 1which gradually or violently as the case may be spread into space, Pro- fessor McLaughlin said. That the star's atmosphere expands and con- tracts may be gathered from the combined study of the star's rate of motion and its change in the bright lines, he showed. In the case of Nova Herculis, its light was+ at first very faint. Then it apparently exploded and increased' in brightness 100,000 times. A study, of the spectrum showed that its line pattern had divided into two parts. The dark lines were displaced and had short wavelengths showing that two masses of gases were moving towards the earth with a velocity of 200 miles per second and 500 miles per second. The bright lines remained with their ((9 FINE JEWELRY is a real reward graduate of 1937. ;. q.. remembrance of a happy graduation.
