Discovery of the Infrared Counterpart of the Rapid Burster with JWST

Malina M. Desai, Kevin B. Burdge, Cristina Pallanca +8

The Rapid Burster (MXB 1730335) is the only known neutron star to produce both Type I and Type II X-ray bursts, making it a key system for understanding accretion physics onto n…

Stars stably accreting from substellar objects

Aaron Householder, Kaitlyn Shin, Kevin B. Burdge +11

Substellar objects such as brown dwarfs and planets are generally expected to remain detached from their main-sequence host stars unless orbital decay or stellar expansion brings t…

A positive period derivative in the quasi-periodic eruptions of ZTF19acnskyy

Joheen Chakraborty, Saul A. Rappaport, Riccardo Arcodia +9

We report the first direct measurement of the period derivative in a quasi-periodic eruption (QPE), finding a smoothly increasing period with $\dot{P}\approx (1.7\pm 0.02)\times10^…

The HD 60779 Planetary System: A Transiting Sub-Neptune on a 30-day Orbit and a More Massive Outer World

Victoria DiTomasso, David Charbonneau, Andrew Vanderburg +37

We present the discovery of the planetary system orbiting the bright (V = 7.2), nearby (35 pc), Sun-like star HD 60779, which has a mass of 1.050 +/- 0.044 solar masses and a radiu…

A gravitational wave detectable candidate Type Ia supernova progenitor

Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty +37

Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evide…

Expanding the ultracompacts: gravitational wave-driven mass transfer in the shortest-period binaries with accretion disks

Joheen Chakraborty, Kevin B. Burdge, Saul A. Rappaport +35

We report the discovery of three ultracompact binary white dwarf systems hosting accretion disks, with orbital periods of 7.95, 8.68, and 13.15 minutes. This significantly augments…

EPIC 220204960: A Quadruple Star System Containing Two Strongly Interacting Eclipsing Binaries

S. Rappaport, A. Vanderburg, T. Borkovits +15

We present a strongly interacting quadruple system associated with the K2 target EPIC 220204960. The K2 target itself is a Kp = 12.7 magnitude star at Teff ~ 6100 K which we design…

Young "Dipper" Stars in Upper Sco and Oph Observed by K2

M. Ansdell, E. Gaidos, S. A. Rappaport +8

We present ten young (10 Myr) late-K and M dwarf stars observed in K2 Campaign 2 that host protoplanetary disks and exhibit quasi-periodic or aperiodic dimming events. Th…

M-Dwarf Fast Rotators and the Detection of Relatively Young Multiple M-Star Systems

S. Rappaport, J. Swift, A. Levine +9

We have searched the Kepler light curves of ~3900 M-star targets for evidence of periodicities that indicate, by means of the effects of starspots, rapid stellar rotation. Several…
