The clumpy absorber in the high-mass X-ray binary Vela X-1
V. Grinberg, N. Hell, I. El Mellah +13
Bright and eclipsing, the high-mass X-ray binary Vela X-1 offers a unique opportunity to study accretion onto a neutron star from clumpy winds of O/B stars and to disentangle the c…
Period Variations for the Cepheid VZ Cyg
Krittanon Sirorattanakul, Scott Engle, Joshua Pepper +4
The Cepheid Period-Luminosity law is a key rung on the extragalactic distance ladder. However, numerous Cepheids are known to undergo period variations. Monitoring, refining, and u…
HST/COS Far Ultraviolet Spectroscopic Analysis of U Geminorum Following a Wide Outburst
Patrick Godon, Michael M. Shara, Edward M. Sion +1
We have used HST/COS to obtain a series of 4 FUV (915-2148A) spectroscopic observations of the prototypical dwarf nova U Geminorum during its cooling following a two-week outburst.…
The magnetic future of the Sun
Philip Judge, RIcky Egeland, Travis Metcalfe +2
We analyze space- and ground-based data for the old (~Gyr) solar analogs 16 Cyg A and B. The stars were observed with the Cosmic Origins UV Spectrographs on the Hubble S…
No Neon, but Jets in the Remarkable Recurrent Nova M31N 2008-12a? - Hubble Space Telescope Spectroscopy of the 2015 Eruption
M. J. Darnley, R. Hounsell, P. Godon +14
The 2008 discovery of an eruption of M31N 2008-12a began a journey on which the true nature of this remarkable recurrent nova continues to be revealed. M31N 2008-12a contains a whi…
Inflows, Outflows, and a Giant Donor in the Remarkable Recurrent Nova M31N 2008-12a? - Hubble Space Telescope Photometry of the 2015 Eruption
M. J. Darnley, R. Hounsell, P. Godon +14
The recurrent nova M31N 2008-12a experiences annual eruptions, contains a near-Chandrasekhar mass white dwarf, and has the largest mass accretion rate in any nova system. In this p…
