Star Grazing with Alumina Grass: Antireflection coatings in the visible and near-infrared on IPX-Clear Microlenses assisted by Grass-like Alumina
Ishan Rana, Suvrath Mahadevan, Megan Delamer +1
Two-photon polymerization (2PP) enables fabrication of high-precision micro-optics with complex freeform geometries, opening a new parameter space for custom astronomical optics. A…
Hipparcos, Gaia, and RVs reveal that the radio emitting F star HD 220242 has an M dwarf companion, a likely source of the radio emission
Megan Delamer, Guðmundur Stefánsson, Suvrath Mahadevan +18
The detection of circularly polarized, low frequency radio emission offers the tantalizing possibility of the observation of interactions between stars and their possible substella…
Discovery of a Nearby Habitable Zone Super-Earth Candidate Amenable to Direct Imaging
Corey Beard, Paul Robertson, Jack Lubin +31
We present the discovery of GJ 251 c, a candidate super-Earth orbiting in the Habitable Zone (HZ) of its M dwarf host star. Using high-precision Habitable-zone Planet Finder (HPF)…
POKEMON: print optimization for kilo-fiber experiments using micro-optics and nanostructures
Megan Delamer, Suvrath Mahadevan, Chad Bender +7
The most pressing problems in modern astrophysics have often required the largest telescopes. With the cost scaling of mirror diameters, the field as a whole is faced with a challe…
Spectroscopic Characterization of LOFAR Radio-emitting M dwarfs
E. Koo, G. Stefansson, R. D. Kavanagh +20
Recent observations with the LOw Frequency ARray (LOFAR) have revealed 19 nearby M dwarfs showing bright circularly polarised radio emission. One of the possible sources of such em…
Searching for GEMS: Confirmation of TOI-5573b, a Cool, Saturn-like Planet Orbiting An M-dwarf
Rachel B Fernandes, Shubham Kanodia, Megan Delamer +35
We present the confirmation of TOI-5573b, a Saturn-sized exoplanet on an 8.79-day orbit around an early M-dwarf (3790 K, 0.59 R, 0.61 M, 12.30 J mag). TOI-5573b has a…
