Effects of XUV radiation on circumbinary planets [PDF]
, 2014 Several circumbinary planets have recently been discovered. The orbit of a planet around a binary stellar system poses several dynamic constraints. The effects that radiation from the host stars may have on the planet atmospheres must be considered ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Short-period Heartbeat Binaries from TESS Full-frame Images
The Astrophysical Journal Supplement SeriesWe identify 240 short-period ( P ≲ 10 days) binary systems in Transiting Exoplanet Survey Satellite data, 180 of which are heartbeat binaries. The sample is mostly a mix of A- and B-type stars and primarily includes eclipsing systems, where over 30% of ...

Merger Conditions of Population III Protostar Binaries
The Astrophysical Journal, 2023 Massive close binary stars with extremely small separations have been observed, and they are possible progenitors of gravitational-wave sources. The evolution of massive binaries in the protostellar accretion stage is key to understanding their formation

Detached white-dwarf close-binary stars -- CV's extended family [PDF]
, 1999 I review detached binaries consisting of white dwarfs with either other white dwarfs or low mass main-sequence stars in tight orbits around them. Orbital periods have been measured for 15 white dwarf/white dwarf systems and 22 white dwarf/M dwarf systems.

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Hot Stars With Cool Companions [PDF]
, 2014 Young intermediate-mass stars have become high-priority targets for direct-imaging planet searches following the recent discoveries of planets orbiting e.g. HR 8799 and Beta Pictoris.

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro
Molecular Oncology, EarlyView.Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

The A Supergiant Eclipsing Binary BM Cas: An Evolved, Intermediate Mass System
The Astronomical JournalThe evolutionary state of the 198 day eclipsing binary BM Cas is examined using spectra that cover five orbital cycles. Radial velocities measured from Si II 6347 and Si II 6371 track the motion of the primary, and a mass function is found that is ...
