Measurement of Distances of Binary Stars [PDF]
WITH reference to Mr. C. E. Stromeyer's letter on the above subject, which appeared on p. 199, it may be of interest to point out that his plan of determining the distance of a binary star is by no means a new one.

STAR MATCHING AND DISTANCE TWO LABELLING
This paper first introduces a new graph parameter. Let $t$ be a positive integer. A $t$-star-matching of a graph $G$ is a collection of mutually vertex disjoint subgraphs $K_{1,i}$ of $G$ with $1 \leq i \leq t$. The $t$-star-matching number, denoted by $SM_t(G)$, is the maximum number of vertices covered by a $t$-star-matching of $G$.

Pulsating stars and the distance scale [PDF]
I present an overview of the latest results from the SH0ES project, which obtained homogeneous Hubble Space Telescope (HST) photometry in the optical and near-infrared for ∼ 3500 and ∼ 2300 Cepheids, respectively, across 19 supernova hosts and 4 calibrators to determine the value of H0 with a total uncertainty of 2.4%.

Magnifying the Early Episodes of Star Formation: Super Star Clusters at Cosmological Distances* [PDF]
Abstract We study the spectrophotometric properties of a highly magnified ( ) pair of stellar systems identified at z = 3.2222 behind the Hubble Frontier Field galaxy cluster MACS J0416.

Measurement of Distances of Binary Stars [PDF]
SOME years ago I communicated to a few astronomers a plan for measuring the distance which separates us from some of the binary stars, believing, as I did, that by using the diameters of their paths as a basis, determinations of distance could be made which are impossible with the means at present in use.

Distance Learning at Future Stars Kindergarten
The Covid-19 pandemic, which began to spread in Indonesia since March 2020, has made many activities to take place at home. The government asks all Indonesians to work from home, worship from home, and learn from home. This is done so that the virus does not spread and cause even greater casualties.

Distance desert automata and the star height problem [PDF]
Let \(\Sigma\) be a given alphabet. The `star height' of a rational expression over \(\Sigma\) is defined inductively as follows: \(\mathbf{sh}(\emptyset):=0\); \(\mathbf{sh}(a):=0\) for all \(a\in\Sigma\); and if \(r\) and \(s\) are regular expressions over \(\Sigma\), then \(\mathbf{sh}(rs)=\mathbf{sh}(r\cup s):=\max\{\mathbf{sh}(r),\mathbf{sh}(s)\}\)
