KMT-2022-BLG-2397: Brown Dwarf at the Upper Shore of the Einstein Desert

The Astronomical Journal, 2023
We measure the Einstein radius of the single-lens microlensing event KMT-2022-BLG-2397 to be θ _E = 24.8 ± 3.6 μ as, placing it at the upper shore of the Einstein Desert, 9 ≲ θ _E / μ as ≲ 25, between free-floating planets (FFPs) and bulge brown dwarfs ...

No large population of unbound or wide-orbit Jupiter-mass planets

, 2017
Gravitational microlensing is the only method capable of exploring the entire population of free-floating planets down to Mars-mass objects, because the microlensing signal does not depend on the brightness of the lensing object.

Characterization of Microlensing Planets with Moderately Wide Separations

, 2009
In future high-cadence microlensing surveys, planets can be detected through a new channel of an independent event produced by the planet itself. The two populations of planets to be detected through this channel are wide-separation planets and free ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Measurement of the Free-Floating Planet Mass Function with Simultaneous Euclid and WFIRST Microlensing Parallax Observations [PDF]

, 2019
Free-floating planets are the remnants of violent dynamical rearrangements of planetary systems. It is possible that even our own solar system ejected a large planet early in its evolution.

Addressing Economic Insecurities Can Improve Patient‐Reported Outcomes in Lupus

Arthritis Care &Research, EarlyView.
Objective Economic insecurities, such as food, housing, transportation, and financial challenges, are modifiable risk factors and influence patient‐reported outcomes (PROs) in systemic lupus erythematosus (SLE). We examined the following: (1) associations between economic insecurities and PROs, and (2) the impact of screening and addressing economic ...

Linking the formation and fate of exo-Kuiper belts within solar system analogues [PDF]

, 2020
Escalating observations of exo-minor planets and their destroyed remnants both passing through the solar system and within white dwarf planetary systems motivate an understanding of the orbital history and fate of exo-Kuiper belts and planetesimal discs.

Microlensing Characterization of Wide-Separation Planets

, 2004
With their excellent photometric precision and dramatic increase in monitoring frequency, future microlensing survey experiments are expected to be sensitive to very short time-scale, isolated events caused by free-floating and wide-separation planets ...

Free-Floating Planets: Not So Surprising

, 2001
We find that free-floating planets can remain bound to a star cluster for much longer than was previously assumed: of the order of the cluster half-mass relaxation timescale as opposed to the crossing-time. This result is based on N-body simulations performed with the new GRAPE-6 special purpose hardware and is important in the context of the ...
