PACS numbers: 98.38.Er,97.10.Fy Purpose: Some peculiarities of emission of Class I methanol masers on the 80–71A+ transition at 95 GHz in sources closely associated with protostar-forming regions and in supernova remnants are studied. Here belongs the investigation of SiO (J=2–1) maser variability in R Cassiopeiaе, too. Design/methodology/approach: Search for Class I methanol masers is based on the idea of coincidence of regions of their emission with sources of OH masing transition in the bottom level of energy at frequency of 1720 MHz (2Π3/2 J=3/2 F=2–1).Findings: Two methanol masers on transition 80–71A+ (95 GHz) in the supernova remnants IC 443 and Kes 79 are detected. Variabilities of SiO maser emission on transition J=2–1 in R Cassiopeiaе are shown for the first time.Conclusions: Variability of methanol and SiO masers is their general feature. On the example of three objects, the possibility of using the 1720 MHz OH maser as an indicator in the search for Class I methanol masers is shown. Especially it is important in the study of methanol maser emission in supernova remnants that has been proved to be true by detection of methanol masers on transition 80–71A+ (95 GHz) in IC 443 and Kes 79. Features of spectra variability of emission in R Cassiopeiaе testify to formation and disappearance of SiO (J=2–1) masers.Key words: maser radiation, supernova remnants, molecular clouds, methanol, SiOManuscript submitted 10.03.2017Radio phys. radio astron. 2017, 22(2): 112-122 REFERENCES1.

Here belongs the investigation of SiO (J=2–1) maser variability in R Cassiopeiaе, too. Design/methodology/approach: Search for Class I methanol masers is based on the idea of coincidence of regions of their emission with sources of OH masing transition in the bottom level of energy at frequency of 1720 MHz (2Π3/2 J=3/2 F=2–1).Findings: Two methanol masers on transition 80–71A+ (95 GHz) in the supernova remnants IC 443 and Kes 79 are detected. Variabilities of SiO maser emission on transition J=2–1 in R Cassiopeiaе are shown for the first time.Conclusions: Variability of methanol and SiO masers is their general feature. On the example of three objects, the possibility of using the 1720 MHz OH maser as an indicator in the search for Class I methanol masers is shown. Especially it is important in the study of methanol maser emission in supernova remnants that has been proved to be true by detection of methanol masers on transition 80–71A+ (95 GHz) in IC 443 and Kes 79. Features of spectra variability of emission in R Cassiopeiaе testify to formation and disappearance of SiO (J=2–1) masers.Key words: maser radiation, supernova remnants, molecular clouds, methanol, SiOManuscript submitted 10.03.2017Radio phys. radio astron. 2017, 22(2): 112-122 REFERENCES1.

DOI:https://doi.org/10.1086/656420 УДК 524.527.7 Предмет и цель работы: Исследуются особенности излучения метанольных мазеров класса І на переходе 80–71A+ (95 ГГц) в областях, ассоциируемых с областями формирования новых протозвезд, и в остатках сверхновых, а также переменность SiO (J= 2–1) мазера в R Cassiopeiaе.Методы и методология: Поиск метанольных мазеров класса I основывается на идее совпадения областей их излучения с областями излучения ОН мазеров на переходе внутри нижнего уровня энергии на частоте 1720 МГц (переход 2Π3/2 J=3/2 F=2–1).Результаты: Обнаружены метанольные мазеры на переходе 80– 71A+ (95 ГГц) в остатках сверхновых IC 443 и Kes 79 и зарегистрированы особенности излучения метанольных мазеров в нескольких объектах, впервые показаны особенности переменности излучения мазера SiO на переходе J= 2–1 в R Cassiopeiaе.Заключение: Переменность метанольных и SiO мазеров является их общим свойством. На примере трех объектов показана возможность использования ОН мазера на частоте 1720 МГц в качестве индикатора при поиске мазеров класса I на молекуле метанола. Особенно это важно при изучении мазерного излучения в остатках сверхновых, что подтверждается обнаружением метанольных мазеров на переходе 80- 71A+ (95 ГГц) в остатках сверхновых IC 443 и Kes 79. Особенности переменности спектров излучения в R Cassiopeiaе свидетельствуют об образовании и исчезновении мазеров SiO на переходе J= 2–1.Ключевые слова: мазерное излучение, остатки сверхновых, молекулярные облака, метанол, SiOСтатья поступила в редакцию 10.03.2017Radio phys. radio astron. 2017, 22(2): 112-122СПИСОК ЛИТЕРАТУРЫ1.

DOI: 10.1086/656420 УДК 524.527.7 Предмет і мета роботи: Досліджуються особливості випромінювання метанольних мазерів класу І на переході 80–71A+ (95 ГГц) у областях, асоційованих з областями формування нових протозірок, і в залишках наднових та змінність SiO (J=2-1) мазера в R Cassiopeiaе.Методи і методологія: Пошук метанольних мазерів класу I ґрунтується на ідеї співпадіння областей їх випромінювання з областями випромінювання ОН мазерів на переході всередині нижнього рівня енергії на частоті 1720 МГц (перехід 2Π3/2 J=3/2 F=2–1).Результати: Виявлено метанольні мазери на переході 80–71A+ (95 ГГц) у залишках наднових IC 443 та Kes 79 і зареєстровано особливості випромінювання метанольних мазерів у декількох об’єктах, вперше показано особливості змінності випромінювання мазера SiO на переході J=2-1 в R Cassiopeiaе.Висновки: Змінність метанольних та SiO мазерів є їхньою спільною властивістю. На прикладі трьох об’єктів показано можливість використання ОН мазера на частоті 1720 МГц у якості індикатора при пошуку мазерів класу I на молекулі метанолу. Особливо це важливо у вивченні мазерного випромінювання в залишках наднових, що підтверджується виявленням метанольних мазерів на переході 80–71A+ (95 ГГц) в залишках наднових IC 443 та Kes 79. Особливості змінності спектрів випромінювання в R Cassiopeiaе свідчать про утворення і зникнення мазерів SiO на переході J=2-1.Ключові слова: мазерне випромінювання, залишки наднових,молекулярні хмари, метанол, SiO Стаття надійшла до редакції 10.03.2017Radio phys. radio astron. 2017, 22(2): 112-122СПИСОК ЛІТЕРАТУРИ1.
