This grant supports research involving observations at radio wavelengths of molecular spectral lines in interstellar clouds and near young stars. The data will be used to deduce the physical conditions within the clouds and to determine the ages of the young stellar objects. In addition funding for this research will enhance the science education of female undergraduates at Wellesley College, with the objective of encouraging them to continue in scientific fields. Students will take an active role in the research, under the guidance of Dr. Benson. This award is made under the auspices of the Research at Undergraduate Institutions program at the National Science Foundation. Gas and dust clouds in the interstellar medium, of the type commonly known as dark molecular clouds, appear to be the sites where stars form. Observations at wavelengths which penetrate the obscuring dusty material indicate the presence of stars or protostars in many such clouds. Radio wavelength observations of spectral lines of molecules such as ammonia have proven to be excellent probes of the physical conditions within the dense cores of the molecular clouds and in the vicinity of newly formed stars.

这项拨款支持涉及无线电观测的研究 星际云中分子谱线的波长， 靠近年轻的恒星。 这些数据将被用来推断 云内的条件，并确定年龄的 年轻的恒星 此外，这项研究的资金将 加强女大学生的科学教育， 韦尔斯利学院，目的是鼓励他们 继续在科学领域。 学生将发挥积极作用 在本森博士的指导下进行研究。 这个奖项是 在本科研究的赞助下， 国家科学基金会的机构计划。 星际介质中的气体和尘埃云， 通常被称为暗分子云， 恒星形成的地方 在穿透大气层的波长上进行观测 模糊的尘埃物质表明恒星的存在， 在许多这样的云中的原恒星。 射电波长观测 氨等分子的光谱线已被证明 对致密核内物理条件的出色探测 分子云和新形成的恒星附近。
