SOME RESULTS OF THE U CrB OBSERVATIONS IN 1856 - 2007
Historical results over of photometry of eclipsing variable star U CrB (type of EA / SD) are brought after 1856 - 2007. Authors suppose that in the system U CrB there is a trade-out by a substance between components.

Sparse Logistic Regression for RR Lyrae versus Binaries Classification
RR Lyrae (RRL) stars are old, low-mass, radially pulsating variable stars in their core helium burning phase. They are popular stellar tracers and primary distance indicators since they obey well-defined period–luminosity relations in the near-infrared ...

Investigating Stellar Variability in the Open Cluster Region NGC 381
We study variable stars in the field of the open cluster NGC 381 using photometric data observed over 27 nights and identify a total of 57 variable stars, six of which are member stars. The variable stars are classified based on their periods, amplitudes,

Photometric studies of be star variability [PDF]
Be stars are hot stars which have shown emission in at least one Balmer line on at least one occasion. As the definition implies, the Be phenomenon can be variable with time: on time scales of days to decades as the circumstellar disc develops and disperses; on time scales of days to months in a few Be stars which are interacting binaries; on time ...

Detection of Variable Stars in the Open Cluster M11 Using Difference Image Analysis Pipeline [PDF]
We developed a photometric pipeline to be used for a wide field survey. This pipeline employs the difference image analysis (DIA) method appropriate for the photometry of star dense field such as the Galactic bulge.

ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...
