A new flare star member candidate in the Pleiades cluster

, 2011
We present a new flare star, which was discovered during our survey on a selected field at the edge of the Pleiades cluster. The field was observed in the period 2007 - 2010 with three different CCD-cameras at the University Observatory Jena with ...

Membership and Multiplicity among Very Low-Mass Stars and Brown Dwarfs in the Pleiades Cluster [PDF]

, 2000
We present near-infrared photometry and optical spectroscopy of very low-mass stars and brown dwarf candidates in the Pleiades open cluster. The membership status of these objects is assessed. Eight objects out of 45 appear to be non-members.

Leveraging Earth Observation Data to Monitor Boat‐Based Recreational Fishing

Fish and Fisheries, Volume 26, Issue 6, Page 1065-1074, November 2025.
High‐resolution satellite imagery was applied to monitor daily patterns of recreational fishing vessels during a temporary fishing ban within a MPA. The satellite detections revealed fine‐scale spatio‐temporal trends not captured by AIS, including a sharp increase in vessel presence immediately after the ban was lifted and a concentration of activity ...

Enhancing the estimation accuracy of above-ground carbon storage in Eucalyptus urophylla plantation on Timor Island, Indonesia, through higher spatial-resolution satellite imagery

Journal of Degraded and Mining Lands Management
Eucalyptus urophylla plantation is an important contributor to carbon storage in climate change mitigation, established due to a land rehabilitation program in the semi-arid ecosystem in Timor Island.

Globular cluster chemistry in fast rotating dwarf stars belonging to intermediate age open clusters [PDF]

, 2018
(shortened) The peculiar chemistry observed in the multiple populations of Galactic globular clusters is not generally found in other systems like dwarf galaxies and open clusters, and at the moment no model can fully explain its presence.

Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

Population Ecology, Volume 67, Issue 4, Page 310-335, October 2025.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

A Search for Photometric Rotation Periods in Low-Mass Stars and Brown Dwarfs in the Pleiades [PDF]

, 1999
We have photometrically monitored (Cousins Ic) eight low mass stars and brown dwarfs which are probable members of the Pleiades. We derived rotation periods for two of the stars - HHJ409 and CFHT-PL8 - to be 0.258 d and 0.401 d, respectively.

Precision‐Arranged DNA Origami Plasmonic Nanoantennas for Multidimensional Smart‐Warning of Weightlessness Induced Bone Loss

Advanced Science, Volume 12, Issue 40, October 27, 2025.
It is synthesized precision‐arranged DNA origami plasmonic nanoantennas for multiplexed and intelligent warning of bone loss induced by microgravity and radiation. The ordered nanoantennas simultaneously and accurately detected calcium ions, interleukin‐6, and microRNA‐214 in serum from mice exposed to microgravity and radiation, with performance ...
