No evidence for activity correlations in the radial velocities of Kapteyn's star
Guillem Anglada-Escudé, Mikko Tuomi, Pamela Arriagada +19
Stellar activity may induce Doppler variability at the level of a few m/s which can then be confused by the Doppler signal of an exoplanet orbiting the star. To first order, linear…
Fabrication of functional 3D nanoarchitectures via atomic layer deposition on DNA origami crystals
Arthur Ermatov, Melisande Kost, Xin Yin +6
While DNA origami is a powerful bottom-up fabrication technique, the physical and chemical stability of DNA nanostructures is generally limited to aqueous buffer conditions. Wet ch…
The MIRI Exoplanets Orbiting White Dwarfs (MEOW) Survey: Mid-Infrared Excess Reveals a Giant Planet Candidate around a Nearby White Dwarf
Mary Anne Limbach, Andrew Vanderburg, Alexander Venner +17
The MIRI Exoplanets Orbiting White dwarfs (MEOW) Survey is a cycle 2 JWST program to search for exoplanets around dozens of nearby white dwarfs via infrared excess and direct imagi…
An Eccentric Sub-Neptune Moving Into the Evaporation Desert
Sydney Jenkins, Andrew Vanderburg, Ritika Sethi +31
Though missions such as Kepler, K2, and TESS have discovered 2,000 sub-Neptune and Neptunian planets, there is a dearth of such planets at close-in (P3 days) orbits. T…
A Quasi-Stationary Solution to Gliese 436b's Eccentricity
Konstantin Batygin, Gregory Laughlin, Stefano Meschiari +3
We investigate the possibility that the large orbital eccentricity of the transiting Neptune-mass planet Gliese 436b is maintained in the face of tidal dissipation by a second plan…
A Pair of Giant Planets around the Evolved Intermediate-Mass Star HD 47366: Multiple Circular Orbits or a Mutually Retrograde Configuration
Bun'ei Sato, Liang Wang, Yu-Juan Liu +19
We report the detection of a double planetary system around the evolved intermediate-mass star HD 47366 from precise radial-velocity measurements at Okayama Astrophysical Observato…
A Neptune-Mass Planet Orbiting the Nearby M Dwarf GJ 436
Paul Butler, Steven S. Vogt, Geoffrey W. Marcy +5
We report precise Doppler measurements of GJ 436 (M2.5V) obtained at Keck Observatory. The velocities reveal a planetary companion with orbital period of 2.644 d, eccentricity of 0…
Diamond-lattice photonic crystals assembled from DNA origami
Gregor Posnjak, Xin Yin, Paul Butler +4
Colloidal self-assembly allows rational design of structures on the micrometer and submicrometer scale. One architecture that can generate complete 3D photonic band gaps is the dia…
Systemic: A Testbed For Characterizing the Detection of Extrasolar Planets. I. The Systemic Console Package
Stefano Meschiari, Aaron Wolf, Eugenio Rivera +3
We present the systemic Console, a new all-in-one, general-purpose software package for the analysis and combined multiparameter fitting of Doppler radial velocity (RV) and transit…
