TECHNICALITIES. “These processes depend on the detailed properties of the WD, in particular, properties of the envelope. In this paper, we consider two CO WD models consisting of a CO core with a He–H envelope.” (WD = white dwarf). https://lnkd.in/djnsGi4 View in LinkedIn

COSMIC POSTAL SYSTEM. “Tidal dissipation in WDs arises from the excitation of gravity waves in the deeper envelope of the WD and their dissipation in the outer envelope.” (WD = white dwarf). https://lnkd.in/djnsGi4 View in LinkedIn

UNFORGETTABLE LITMUS TEST. “Is this brilliance or complicated nonsense?” (Cartoonist of Shoe, Jeff MacNelly, whose brilliant epithet has been lost in the bowels of time). Once kept on a suspended baseball bat over my desk. Never forget this one! https://lnkd.in/dCstGxV View in LinkedIn

INEVITABLE QUESTION. “A major goal of this paper is to determine the tidal energy and angular momentum transfer rates for a WD in a high-eccentricity orbit around an MBH.” (WD = white dwarf; MBH = Massive Black Hole). https://lnkd.in/djnsGi4 View in LinkedIn

LOWER LIMIT. “An otherwise quiet MBH would show bright, beamed emission after the disruption of a WD. Therefore, detecting (or not detecting) signals from the tidal disruptions of WDs could place constraints on the MBH population.” (WD = white dwarf; MBH = Massive Black Hole). https://lnkd.in/djnsGi4 View in LinkedIn

VERIFIED. “There are now a few cases in which hard X-ray emission from launching a relativistic jet was observed following a flare from stellar disruption.” https://lnkd.in/djnsGi4 View in LinkedIn

PREDICTION. “We expect these disruption events to be very luminous as a portion of the accretion power likely channels into a relativistic jet.” https://lnkd.in/djnsGi4 View in LinkedIn

MASS DEPENDENT. “The possibility of detecting WD-TDEs is especially intriguing because the disruption of a WD is only visible if the mass of the BH, Mbh, is less than about 10(5) M⊙ or perhaps 10(6) M⊙ depending on the BH spin. For a more massive BH, the WD is ‘swallowed whole’ without disruption.” (WD = white dwarf; TDE = tidal disruption event). https://lnkd.in/djnsGi4 View in LinkedIn

IMPLICATIONS. “Our study of tidal dissipation in eccentric WD–MBH binaries can be easily adapted to other problems. For instance, WD–WD binaries with extreme eccentricities may be produced in triple systems, which could lead to direct WD–WD collisions and Type Ia supernovae.” (WD = white dwarf; MBH = massive black hole). https://lnkd.in/djnsGi4 View in LinkedIn
