“…The EW of observed spectral lines varies depending on the observation epoch. These spectral line variations are consistent with previous studies (Hillenbrand 2019;Giannini et al 2022), which show different line profiles depending on the brightness of Gaia19fct.…”

“…The broad single-peaked line profiles can form at the rotating protostellar photosphere (Gray 1992). The observed NIR metallic lines show U-like or boxy profiles, similar to optical lines presented by Hillenbrand (2019), rather than a clear double-peaked profile. In order to investigate the origin of the metallic lines, we fitted these atomic absorption lines with the standard stellar spectrum from the IGRINS Spectral Library (Park et al 2018) by convolving with disk rotational and stellar rotational profiles described in Yoon et al (2021).…”

“…Based on the amplitude of its brightening and rich emission lines, Gaia19fct was suggested as a new EXor (Miller et al 2015). Repeated brightenings in 2018 and 2019 were reported by Hillenbrand (2019). The brightening in 2019 (ΔG > 4 mag) was reported by the Gaia Photometric Science Alerts Program on 2019 November 14.…”

“…Gaia19fct has been studied in several works (Miller et al 2015;Hillenbrand 2019;Giannini et al 2022) after its discovery in 2015 (Miller et al 2015). Since 2015, at least five burst events have occurred, and each of these events shows a different amplitude, duration, and speed of brightness variation (Δ mag/Δt; Section 4.3.1), indicating that, similar to the classical EXor V1118 Ori (Giannini et al 2020), these bursts are not the periodic repetition of the same event.…”

“…Giannini et al (2022) presented optical and NIR spectra of Gaia19fct. The quiescent spectrum is dominated by emission lines, while the outburst spectrum is dominated by absorption lines (Hillenbrand 2019;Giannini et al 2022). The overall amplitudes, timescales of brightness events, and spectroscopic properties of Gaia19fct are more similar to EXors.…”

Gaia19fct is one of the Gaia-alerted eruptive young stars that has undergone several brightening events. We conducted monitoring observations using multifilter optical and near-infrared photometry, as well as near-infrared spectroscopy, to understand the physical properties of Gaia19fct and investigate whether it fits into the historically defined two classes. We present the analyses of light curves, color variations, spectral lines, and CO modeling. The light curves show at least five brightening events since 2015, and the multifilter color evolutions are mostly gray. The gray evolution indicates that bursts are triggered by mechanisms other than extinction. Our near-infrared spectra exhibit both absorption and emission lines and show time variability throughout our observations. We found lower rotational velocity and lower temperature from the near-infrared atomic absorption lines than from the optical lines, suggesting that Gaia19fct has a Keplerian rotating disk. The CO overtone features show a superposition of absorption and emission components, which is unlike other young stellar objects. We modeled the CO lines, and the result suggests that the emission and absorption components are formed in different regions. We found that although Gaia19fct exhibits characteristics of both types of eruptive young stars, FU Orionis–type objects and EX Lupi–type objects, it shows more similarity with EXors in general.

İbadet mekanları bütün uygarlıklarda en önemli yapıların arasında yer almıştır. İslam dininin temel ibadet mekânı Arapçada mescid denilen mekandır. İslam dininin kutsal kitabı Kuran'da her ne kadar cami mimarisine doğrudan bir tanımlama yapılmasa da bütün dinlerde olduğu gibi kutsal bir alan yaratmak ve dini ritüellerin uygulanmasına karşılık vermek esas alınarak belli özelliklere sahip olan bir ibadet mekânı ortaya çıkmıştır (Hamzenejad ve Arabi, 2014).İslam dininin büyük bir coğrafyaya yayılması neticesinde camiler İslam tarihi boyunca kültürel ve iklimsel etkenler, kullanılan malzeme ve günün teknolojisine göre farklı uygulamalarla farklı biçimlerde oluşmuştur. Böylece İslam dini ortaya çıkıp yayılmaya başladığından bu yana cami yapısı zaman içinde değişime direnmemiştir. Aksine karşılaştığı birçok kültürün mimari üslup özelliklerini benimseyerek çağının en ileri teknolojisini temsil eden yapı türü olmuştur (Güzer, 2009). Ancak bu yaklaşım 17.yy. a kadar devam etmiştir * Bu makale ilk yazarın BAP projesi kapsamında gerçekleşen yüksek lisans tezinden üretilmiştir.

Every civilization produces places that match the life model in its own content. In this context, Islamic Civilization has also built mosques as temples within its own structure. The formation and development of mosque architecture has taken shape by adding some visual elements to its architecture with the principles of Islamic Civilization. These elements are almost identified with mosque architecture and have been interpreted and included in mosques built all over the world. With the influence of developments in the construction industry and modern architecture, different searches have occurred in mosque architecture. While some of the mosques built in this way are a repetition or a bad imitation of the traditional, some have been transformed to avoid this repetition and have become foreign architectures that are incompatible with the civilization they belong to. Both situations have negative effects on the mosque architecture and led to the reproduction of them of kitsch designs. This study was carried out to read the architecture of the mosques produced with the interpretation of traditional mosque architecture, rather than repetition in different geographies of the world, and in order to question whether they meet the expectation of mosque architecture. In this context, a survey technique was applied to a population of 100 people, 32% of whom were architects and 96% were Muslims. The data obtained from the survey results were analyzed and evaluated in the SPSS program. Thus, the place and importance of the architectural elements of traditional mosques in mosque architecture, the existence of these elements in modern mosques, and the meanings of traditional-modern lines in mosques have been examined. It is thought that this study, which was prepared by using a questionnaire about 22 modern mosques selected from different geographies of the world, will contribute to the development of mosque architecture without repetition and losing its identity.
