Despite the challenges of the remote mode, we have had a very successful program of Summer 2020 undergraduate research! We thank NASA and Space@Hopkins<\/a> for timely support of the summer 2020 research program on a short notice, and we were grateful for the opportunity to present the results of our program to NASA Headquarters.<\/p>\n\n\n\n

A quadruple stellar system discovered by Gavin Fezenko and Hsiang-Chih Hwang. Each of the two bright stars marked with red arrows is actually a close stellar binary, with light curves showing eclipses in the insets. <\/figcaption><\/figure>\n\n\n\n

Mansha Kapur<\/strong> (advisors: Hsiang-Chih Hwang, Nadia Zakamska) worked on identifying companions to neutron stars in the Gaia dataset. <\/p>\n\n\n\n

Gavin Fezenko <\/strong>(advisors: Hsiang-Chih Hwang, Nadia Zakamska) worked on identifying quadruple stellar systems consisting of two very close binaries.

Devon Williams<\/strong> (advisors: Caroline Huang, Nadia Zakamska) modeled spatially resolved spectroscopy of galaxies obtained using the integral-field unit technique. 

Kyle Schneider<\/strong> (advisors: David Nataf, Nadia Zakamska) investigated light curves of Mira variables and identified Mira stars associated with Galactic globular clusters. 

Carsten Langholm<\/strong> (advisors: Hsiang-Chih Hwang, Nadia Zakamska) explored modern computational methods for measuring periods and period changes from the light curves of periodic objects. 

Brandon Stride<\/strong> (advisors: Hsiang-Chih Hwang, Nadia Zakamska) investigated variable young stellar objects — `dippers’ — and the wavelength dependence of their variability to constrain the physical properties of the protostellar disks. 

Matt Kleiman<\/strong> (advisors: Hsiang-Chih Hwang, Nadia Zakamska) looked for young eclipsing binaries — those that still have protostellar material surrounding the binary.  

Felix Yu<\/strong> (advisors: Vedant Chandra, Nadia Zakamska) explored modern computational methods for analyzing spectra of white dwarfs, especially for identifying interesting and unusual objects. 

John Magardino<\/strong> (advisors: Vedant Chandra, Nadia Zakamska) investigated magnetic white dwarfs and analyzed their atmospheric absorption features to measure the strength of the Zeeman effect. 

Evan Petrosky<\/strong> and Vedant Chandra<\/strong> continued their projects from Summer 2019 with Nadia Zakamska and Hsiang-Chih Hwang. Vedant Chandra has published two papers on his research so far: “Computational tools for spectroscopic analysis of white dwarfs<\/a>” and “A gravitational redshift measurement of the white dwarf equation of state<\/a>.” The second paper was highlighted in the JHU HUB article<\/a> and in Science News<\/a>.

IDIES Summer Fellowship recipient Vedant Chandra<\/strong> (advisor Kevin Schlaufman) used machine learning to differentiate between cool white dwarfs and metal-poor main sequence stars and then conducted a search for low-mass Population III stars in the Sloan Digital Sky Survey.

Turner Woody<\/strong> (advisor Kevin Schlaufman) calculated the orbits of the Milky Way’s globular clusters and used those data in concert with literature age and metallicity inferences to construct a more general model for the assembly of massive galaxies’ globular cluster systems.<\/p>\n\n\n\n
