Study of globular cluster M53: new variables, distance, metallicity [PDF]

Astronomy and Astrophysics, 2009
We study the variable star content of the globular cluster M53 to compute the physical parameters of the constituting stars and the distance of the cluster.

Unraveling the multifaceted resilience of arsenic resistant bacterium Deinococcus indicus [PDF]

Frontiers in Microbiology, 2023
Arsenic (As) is a toxic heavy metal widely found in the environment that severely undermines the integrity of water resources. Bioremediation of toxic compounds is an appellative sustainable technology with a balanced cost-effective setup.

CN Bimodality at Low Metallicity: The Globular Cluster M53 [PDF]

Publications of the Astronomical Society of the Pacific, 2007
We present low resolution UV-blue spectroscopic observations of red giant stars in the globular cluster M53 ([Fe/H]=-1.84), obtained to study primordial abundance variations and deep mixing via the CN and CH absorption bands. The metallicity of M53 makes

Investigation of variable star candidates in the globular cluster NGC 5024 (M53) [PDF]

Monthly Notices of the Royal Astronomical Society, 2012
We have performed a careful investigation of the 74 candidate variable stars presented by Safanova & Stalin (2011). For this purpose we used our data base of imaging and light curves from Arellano Ferro et al. (2011) and Arellano Ferro et al. (2012).

Erythritol production by Yarrowia lipolytica mutant strain M53 generated through atmospheric and room temperature plasma mutagenesis [PDF]

Food Science and Biotechnology, 2017
Mutants of Yarrowia lipolytica with high erythritol production were generated through an atmospheric and room temperature plasma (ARTP) mutation system. Among these mutants, Y. lipolytica M53 exhibited the highest erythritol yield. In a batch culture, M53 produced 64.8 g/L erythritol from 100 g/L glycerol. The yields of byproducts (e.g.

Dominant Negative Mutants of the Murine Cytomegalovirus M53 Gene Block Nuclear Egress and Inhibit Capsid Maturation [PDF]

Journal of Virology, 2010
ABSTRACT The alphaherpesvirus proteins UL31 and UL34 and their homologues in other herpesvirus subfamilies cooperate at the nuclear membrane in the export of nascent herpesvirus capsids. We studied the respective betaherpesvirus proteins M53 and M50 in mouse cytomegalovirus (MCMV).

RELATIVE AGE DIFFERENCE BETWEEN THE METAL-POOR GLOBULAR CLUSTERS M53 AND M92

Journal of the Korean Astronomical Society, 2016
CCD photometric observations of the globular cluster (GC), M53 (NGC 5024), are performed using the 1.8 m telescope at the Bohyunsan Optical Astronomy Observatory in Korea on the same nights (2002 April and 2003 May) as the observations of the GC M92 (NGC 6341) reported by Cho and Lee using the same instrumental setup.

The Blue Straggler population in the globular cluster M53 (NGC5024): a combined HST, LBT, CFHT study

, 2008
We used a proper combination of multiband high-resolution and wide field multi-wavelength observations collected at three different telescopes (HST, LBT and CFHT) to probe Blue Straggler Star (BSS) populations in the globular cluster M53.

Exploring the variable stars in the globular cluster NGC 5024 (M53): new RR Lyrae and SX Phoenicis stars★

Monthly Notices of the Royal Astronomical Society, 2011
We report CCD V and I time series photometry of the globular cluster NGC 5024 (M53). The technique of difference image analysis has been used which enables photometric precisions better than 10 mmag for stars brighter than V 18.5mag even in the crowded central regions of the cluster.

On the Variability of Blue Straggler Stars in the Globular Cluster M53 [PDF]

Journal of Astronomy and Space Sciences, 1998
We present the results of a search for photometric variable blue straggler stars (BSSs) in the globular cluster M53. Six of the 151 probable BSSs are identified as variable candidates based on the robust variable star detection technique of Welch ...
