The Pleiades are a cluster of fungal effectors that inhibit host defenses.

open access: yesPLoS Pathogens, 2021
Biotrophic plant pathogens secrete effector proteins to manipulate the host physiology. Effectors suppress defenses and induce an environment favorable to disease development.

Pleiades or Not? Resolving the Status of the Lithium Rich M Dwarfs HHJ339 and HHJ430 [PDF]

open access: yesAstronomical Journal, 2020
Oppenheimer et al. (1997) discovered two M5 dwarfs in the Pleiades with nearly primordial lithium. These stars are not low enough in mass to represent the leading edge of the lithium depletion boundary at Pleiades age (~125 Myr). A possible explanation for the enhanced lithium in these stars is that they are actually not members of the Pleiades but ...

The problem of the Pleiades distance. Constraints from Stromgren photometry of nearby field stars [PDF]

open access: bronze, 2001
The discrepancy between the Pleiades cluster distance based on Hipparcos parallaxes and main sequence fitting is investigated on the basis of Stromgren photometry of F-type stars. Field stars with the same metallicity as the Pleiades have been selected from the m1 index and a technique has been developed to locate the ZAMS of these field stars in color-

A census of the near-by Pisces-Eridanus stellar stream -- Commonalities with and disparities from the Pleiades [PDF]

open access: yesA&A 638, A9 (2020), 2020
Within a 400~pc sphere around the Sun, we search for members of the Pisces-Eridanus (Psc-Eri) stellar stream in the Gaia Data Release 2 (DR2) data set. We compare basic astrophysical characteristics of the stream with those of the Pleiades. We used a modified convergent-point method to identify stars with 2D - velocities consistent with the space ...

Observations of the core of the Pleiades with the Chandra X-ray Observatory [PDF]

open access: bronze, 2000
We present results from a 36-ksec observation of the core of the Pleiades open cluster using ACIS-I on the Chandra X-ray Observatory. We have detected 57 sources, most of which do not have previously known optical counterparts. Follow-up photometry indicates that many of the detections are likely to be AGNs, in accordance with extragalactic source ...

Aastronomical and calendar meaning of the petroglyphs of the dolmen "Dudugush-1". Reconstruction of some cosmological motives in the culture of the dolmen builders of the Western Caucasus [PDF]

open access: yesArchaeoastronomy and Ancient Technologies, 2021
The article is considered astronomical and calendarian meaning of the petroglyth on the overlapping of the dolmen "Dudugush-1". As shown enclosing in the circle the branches of the saltire note the key points of the year solar cycle (sunrises and sunsets

TESTING DIFFERENT VALUES OF SEGMENTATION SCALE PARAMETER IN THE FUNCTION OF DETECTION OF ILLEGAL WASTE LANDFILLS [PDF]

open access: yesGeodetski Glasnik, 2021
Illegal waste landfills are a current problem facing a large number of countries. In order to control and better manage illegal landfills, it is necessary to know the updated locations and contents of illegal landfills. Remote sensing methods have proven

Unresolved Binaries in the Intermediate Mass Range in the Pleiades Star Cluster [PDF]

open access: yesAstronomical Journal, 2022
The identification of binary stars of different mass ratios in resolved stellar populations is a challenging task. We show how the photometric diagram constructed with the pseudocolors (H-W2)-W1 versus W2-(BP-K) can be employed to estimate the binary and

Starspots and Magnetism: Testing the Activity Paradigm in the Pleiades and M67 [PDF]

open access: yes, 2022
We measure starspot filling fractions for 240 stars in the Pleiades and M67 open star clusters using APOGEE high-resolution H-band spectra. For this work we developed a modified spectroscopic pipeline which solves for starspot filling fraction and ...
