Case studies of photospheric magnetic field properties of active regions associated with X-class solar flares by Teh, Wai-Leong, Farahana Kamarudin

“…The ARs are accompanied with strong magnetic fields and manifested as dark spots on the photosphere. To understand the photospheric magnetic field properties of the ARs that produce intense flares, two ARs associated with X-class flares, namely AR 12192 and AR 12297, occurred respectively on 25 October 2014 and 11 March 2015, are studied in terms of magnetic classification and various physical magnetic parameters. …”

Optically thick outflows in ultraluminous supersoft sources by Urquhart, Ryan, Soria, Roberto

“…We suggest that in ULSs, the massive disc outflow becomes effectively optically thick and forms a large photosphere, shrouding the inner regions from our view. …”

Revisiting the ultraluminous supersoft source in M 101: An optically thick outflow model by Soria, Roberto, Kong, A.

“…We develop a simple, spherically symmetric outflow model and show that it is consistent with the observed temperatures, radii and luminosities. A larger, cooler photosphere shifts the emission peak into the far-UV and makes the source dimmer in X-rays but possibly ultraluminous in the UV. …”

A tidal disruption event coincident with a high-energy neutrino by Stein, R., Velzen, S.V., Kowalski, M., Franckowiak, A., Gezari, S., Miller-Jones, James, Frederick, S., Sfaradi, I., Bietenholz, M.F., Horesh, A., Fender, R., Garrappa, S., Ahumada, T., Andreoni, I., Belicki, J., Bellm, E.C., Böttcher, M., Brinnel, V., Burruss, R., Cenko, S.B., Coughlin, M.W., Cunningham, V., Drake, A., Farrar, G.R., Feeney, M., Foley, R.J., Gal-Yam, A., Golkhou, V.Z., Goobar, A., Graham, M.J., Hammerstein, E., Helou, G., Hung, T., Kasliwal, M.M., Kilpatrick, C.D., Kong, A.K.H., Kupfer, T., Laher, R.R., Mahabal, A.A., Masci, F.J., Necker, J., Nordin, J., Perley, D.A., Rigault, M., Reusch, S., Rodriguez, H., Rojas-Bravo, C., Rusholme, B., Shupe, D.L., Singer, L.P., Sollerman, J., Soumagnac, M.T., Stern, D., Taggart, K., van Santen, J., Ward, C., Woudt, P., Yao, Y.

“…Our electromagnetic observations can be explained through a multizone model, with radio analysis revealing a central engine, embedded in a UV photosphere, that powers an extended synchrotron-emitting outflow. …”

Magnetic fields in isolated and interacting white dwarfs by Ferrario, L., Wickramasinghe, D., Kawka, Adela

“…The situation may be similar in magnetic binaries because the bright accretion discs in low field systems hide the photosphere of their WDs thus preventing the study of their magnetic fields’ strength and structure. …”

The characteristics of be star in delta scorpii system / Nazhatulshima Ahmad by Nazhatulshima, Ahmad

“…The circumstellar regions of H, H, H, and HeI λ6678 and photospheric region which are represented by HeI λ4388, HeII λ4686, MgII λ4481 and HeI λ4921 have been used in the investigation of the Be disk of -Scorpii. …”
