Shaking on Impact

When objects impact water with enough speed, they create a smooth-walled, air-filled cavity around and behind them. Here, the impacting object is one with some give, like a spring. (Image credit: J. Antolik et al.) Read the full article

"ABSTRACT:"

"Stars form from the gravitational collapse of turbulent, magnetized molecular cloud cores. Our non-ideal MHD simulations reveal that the intrinsically anisotropic magnetic resistance to gravity during the core collapse naturally generates dense gravomagneto sheetlets within inner protostellar envelopes – disrupted versions of classical sheet-like pseudo-discs. They are embedded in a magnetically dominant background, where less dense materials flow along the local magnetic field lines and accumulate in the dense sheetlets. The sheetlets, which feed the disc predominantly through its upper and lower surfaces, are the primary channels for mass and angular momentum transfer from the envelope to the disc. The protostellar disc inherits a small fraction (up to 10 per cent) of the magnetic flux from the envelope, resulting in a disc-averaged net vertical field strength of 1–10 mG and a somewhat stronger toroidal field, potentially detectable through ALMA Zeeman observations.

The inherited magnetic field from the envelope plays a dominant role in disc angular momentum evolution, enabling the formation of gravitationally stable discs in cases where the disc field is relatively well-coupled to the gas. Its influence remains significant even in marginally gravitationally unstable discs formed in the more magnetically diffusive cases, removing angular momentum at a rate comparable to or greater than that caused by spiral arms. The magnetically driven disc evolution is consistent with the apparent scarcity of prominent spirals capable of driving rapid accretion in deeply embedded protostellar discs. The dense gravomagneto sheetlets observed in our simulations may correspond to the ‘accretion streamers’ increasingly detected around protostars."

“Paper to pen

Riding the pain

Time to move pass

Past to get pass

Passing the memory

All in your memory

Feelings you lent to me

Shrugging it off

Lost in my head

Found it at odds

When it all even

And it’s all gone

Who’s to give water replenish my energy

When i'm not strong

Taking it back

Fearing it all

Hoping to jump

Never to fall

Fall in space

Falling from grace

Loving your smile

Severed erased”

-A Mother’s Lullaby (Airospace)

RU’AHH & THE INFINITE OCEAN

We’ve discussed the opening line of Genesis and alluded to a deeper meaning behind the concept of the opening words. Now let’s expand on the Hebrew and jump into the land of infinite possibilities. We see Solomons Woman Wisdom take center stage as we dance through the Alchemical Mysteries that stretch back to Kemet. Click the link and take that journey within.

Grenouille arabesque

Incognito jusqu’au bout des doigts Je sautille à gauche, à droite, dans le coin, à l’ombre du parapet Petite fugue dans la nuit des menaces sur mon coeur réparé. Qui a mangé les bonbons? On ne saura jamais. Mais on aura ri, Et aussi un peu pleuré.

Ploc ploc ploc, c’est le rejet qui parle Plouf plouf plouf c’est le plongeon en terre de colère et de honte

Je courre à demi, mi citron mi poisson Oeuf en sucre-sueur qui ne fond pas mais se consume

Suis-je devenue autruche ou bien anguille?

Politique du soin, éthique de la traduction

Ici et là-bas je fais la loutre

Je gaffe, je bafouille, je ventriloque

Leçons de soin en dents de scie J’oscille

"An international research team led by Michael Kramer and Kuo Liu from the Max Planck Institute for Radio Astronomy in Bonn, Germany, have studied magnetars to uncover an underlying law that appears to apply universally to neutron stars."

"To their surprise, the researchers found that the timescale of magnetars and that of the other types of neutron stars all follow the same universal relationship, scaling exactly with the rotation period. The fact that a neutron star with a rotation period of less than a few milliseconds and one with a period of nearly 100 seconds behave like magnetars suggests that the intrinsic origin of the subpulse structure must be the same for all radio-loud neutron stars.

This reveals information about the plasma process responsible for the radio emission itself, and it offers a chance to interpret similar structures seen in FRBs as the result of a corresponding rotational period.

"When we set out to compare magnetar emission with that of FRBs, we expected similarities," says Michael Kramer, first author of the paper and Director at MPIfR. "What we didn't expect is that all radio-loud neutron stars share this universal scaling."

"We expect magnetars to be powered by magnetic field energy, while the others are powered by their rotational energy," says Kuo Liu. "Some are very old, some are very young, and yet all seem to follow this law.""

For example, when soybean plants, which are SDPs, are transferred from an 8-h light period to an extended 64-h dark period, the flowering response to night breaks shows a circadian rhythm (Figure 20.9). (...) As shown in Figure 20.9, the phases of sensitivity and insensitivity to light continue to oscillate in the darkness.
