Цель данной работы – статистически сравнить свойства рентгеновской светимости этих двух классов HMXB, в частности максимальную светимость и диапазон ее изменчивости . Для этого использованы каталожные данные по галактическим HMXB-пульсарам (18 постоянных и 64 транзиентных систем). Проанализированы распределения и с помощью гистограмм, коробчатых диаграмм (boxplot), кумулятивных кривых (CDF) и непараметрического критерия Манна–Уитни. Показано, что оба класса достигают сходных значений (порядка – эрг/с), без статистически значимого расхождения распределений. Однако транзиентные системы демонстрируют значительно более широкий диапазон изменчивости светимости: увеличение на 4–5 порядков (до раз) против обычно менее раз у постоянных. Это отличие подтверждается статистически (для транзиентов выявлена более высокая вариабельность, p ≈ 0.05). Таким образом, основное различие между постоянными и транзиентными HMXB заключается не в предельной рентгеновской светимости, а в режиме аккреции. В постоянных системах компактный объект непрерывно аккрецирует вещество из устойчивого звездного ветра OB-сверхгиганта, обеспечивая относительно стабильное излучение. Напротив, транзиенты характеризуются прерывистой аккрецией (например, эпизодическим захватом материи из диска Be-звезды), что приводит к их экстремальной вариабельности.</p></abstract><trans-abstract xml:lang="en"><p>High-mass X-ray binaries (HMXBs) are commonly divided into persistent sources, which emit X-rays steadily over long periods, and transient sources, which remain mostly in a quiescent state and exhibit episodic X-ray outbursts. The aim of this work is to statistically compare the X-ray luminosity properties of these two classes, focusing on the maximum luminosity and the luminosity variability range . For this purpose, catalog data for Galactic HMXB pulsars were used, including 18 persistent and 64 transient systems. The distributions of and were analyzed using histograms, box plots, cumulative distribution functions (CDFs), and the non-parametric Mann–Whitney test. It is shown that both classes reach similar values of on the order of – erg/s), with no statistically significant difference between their distributions. However, transient systems exhibit a much wider luminosity variability range, reaching increases of 4–5 orders of magnitude (up to ), whereas persistent sources typically show lower variability. This difference is statistically confirmed, with transients demonstrating significantly higher variability p ≈ 0.05). Thus, the main distinction between persistent and transient HMXBs lies not in their peak X-ray luminosity, but in their accretion regime. In persistent systems, the compact object continuously accretes matter from a relatively stable stellar wind of an OB supergiant, resulting in steady X-ray emission. In contrast, transient systems are characterized by intermittent accretion (for example, episodic mass capture from a Be-star circumstellar disc), which leads to their extreme luminosity variability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>высокомассивные рентгеновские двойные</kwd><kwd>HMXB</kwd><kwd>транзиентные источники</kwd><kwd>рентгеновская светимость</kwd><kwd>аккреция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>high-mass X-ray binaries</kwd><kwd>HMXBs</kwd><kwd>transient sources</kwd><kwd>X-ray luminosity</kwd><kwd>accretion</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research is funded by the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan (Grant No. AP23489541).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Reig, P.
